Cobalt Red: How the Blood of the Congo Powers Our Lives

Introduction

Such then was the main task: to convince the world that thgis Congo horror was not only and unquestionably a fact; but that it was not accidental or temporary, or capable of internal cure … To demonstrate that it was at once a survival and a revival of the slave-mind at work, of the slave-trade in being.

—E. D. Morel, History of the Congo Reform Movement, 1914

THE SOLDIERS ARE WILD and wide-eyed as they point their weapons at the villagers trying to enter the mining area at Kamilombe. Although they are desperate to reach their loved ones just a stone’s throw away, the villagers are denied access. What has happened here must not be seen. There can be no record or evidence, only the haunting memories of those who stood at this place where hope was lost. My guide urges me to stay at the periphery; the situation is too unpredictable. From the fringes, it is difficult to see the details of the accident. The craterous landscape is obscured by a leaden haze that refuses the entry of light. Distant hills appear only as the vague silhouette of a lumbering beast.

I move closer to investigate, treading carefully into the boiling crowd. I catch sight of a body in the dirt. It is a child, lying motionless within a storm of dust and despair. I try to make out the features of his face, but they elude me. Around the lifeless body, the ocher gravel has been stained in dark shades of red, like burnt umber or rusted metal. Until this moment, I thought that the ground in the Congo took its vermillion hue from the copper in the dirt, but now I cannot help but wonder whether the earth here is red because of all the blood that has spilled upon it.

I inch toward the cordon to see the child more clearly. Tensions between the soldiers and villagers escalate to the brink of riot. A soldier shouts angrily and waves his gun at me. I’ve drifted too close and lingered too long. I take one final look toward the child. I can see his face now, locked in a terminal expression of dread. That is the lasting image I take from the Congo—the heart of Africa reduced to the bloodstained corpse of a child, who died solely because he was digging for cobalt.

There is a frenzy taking place in the Democratic Republic of the Congo, a manic race to extract as much cobalt as quickly as possible. This rare, silvery metal is an essential component to almost every lithium-ion rechargeable battery made today. It is also used in a wide array of emerging low-carbon innovations that are critical to the achievement of climate sustainability goals. The Katanga region in the southeastern corner of the Congo holds more reserves of cobalt than the rest of the planet combined. The region is also brimming with other valuable metals, including copper, iron, zinc, tin, nickel, manganese, germanium, tantalum, tungsten, uranium, gold, silver, and lithium. The deposits were always there, resting dormant for eons before foreign economies made the dirt valuable. Industrial innovations sparked demand for one metal after another, and somehow they all happened to be in Katanga. The remainder of the Congo is similarly bursting with natural resources. Foreign powers have penetrated every inch of this nation to extract its rich supplies of ivory, palm oil, diamonds, timber, rubber … and to make slaves of its people. Few nations are blessed with a more diverse abundance of resource riches than the Congo. No country in the world has been more severely exploited.

The scramble for cobalt is reminiscent of King Leopold II’s infamous plunder of the Congo’s ivory and rubber during his brutal reign as king sovereign of the Congo Free State from 1885 to 1908. Those familiar with Leopold’s regime may reasonably point out that there is little equivalency between the atrocities that took place during his time and the harms taking place today. To be sure, the loss of life during Leopold’s control of the Congo is estimated to be as high as thirteen million people, a sum equal to half the population of the colony at the time. Today, the loss of life caused either directly by mining accidents or indirectly by toxic exposure and environmental contamination in the mining provinces would likely be a few thousand per year. One must acknowledge, however, the following crucial fact—for centuries, enslaving Africans was the nature of colonialism. In the modern era, slavery has been universally rejected and basic human rights are deemed erga omnes and jus cogens in international law. The ongoing exploitation of the poorest people of the Congo by the rich and powerful invalidates the purported moral foundation of contemporary civilization and drags humanity back to a time when the people of Africa were valued only by their replacement cost. The implications of this moral reversion, which is itself a form of violence, stretch far beyond central Africa across the entire global south, where a vast subclass of humanity continues to eke out a subhuman existence in slave-like conditions at the bottom of the global economic order. Less has changed since colonial times than we might care to admit.

The harsh realities of cobalt mining in the Congo are an inconvenience to every stakeholder in the chain. No company wants to concede that the rechargeable batteries used to power smartphones, tablets, laptops, and electric vehicles contain cobalt mined by peasants and children in hazardous conditions. In public disclosures and press releases, the corporations perched atop the cobalt chain typically cite their commitments to international human rights norms, zero-tolerance policies on child labor, and adherence to the highest standards of supply chain due diligence. Here are a few examples:¹

Apple works to protect the environment and to safeguard the well-being of the millions of people touched by our supply chain, from the mining level to the facilities where products are assembled … As of December 31, 2021, we found that all identified smelters and refiners in our supply chain participated in or completed a third party audit that met Apple’s requirements for the responsible sourcing of minerals.

Samsung has a zero-tolerance policy against child labor as prohibited by international standards and relevant national laws and regulations in all stages of its global operations.

While Tesla’s responsible sourcing practices apply to all materials and supply chain partners, we recognize the conditions associated with select artisanal mining (ASM) of cobalt in the DRC. To assure the cobalt in Tesla’s supply chain is ethically sourced, we have implemented targeted due diligence procedures for cobalt sourcing.

For Daimler, respect for human rights is a fundamental aspect of responsible corporate governance … We want our products to contain only raw materials and other materials that have been mined and produced without violating human rights and environmental standards.

Glencore plc is committed to preventing the occurrence of modern slavery and human trafficking in our operations and supply chains … We do not tolerate child labour, any form of forced, compulsory or bonded labour, human trafficking or any other form of slavery and actively seek to identify and eliminate them from our supply chains.

As scrutiny over the conditions under which cobalt is mined has increased, stakeholders have formulated international coalitions to help ensure that their supply chains are clean. The two leading coalitions are the Responsible Minerals Initiative (RMI) and the Global Battery Alliance (GBA). The RMI promotes the responsible sourcing of minerals in accordance with the UN Guiding Principles for Business and Human Rights. Part of the RMI’s platform includes a Responsible Minerals Assurance Process that purports to support independent, third-party assessments of cobalt supply chains and to monitor cobalt mining sites in the DRC for child labor. The GBA promotes safe working conditions in the mining of raw materials for rechargeable batteries. The GBA has developed a Cobalt Action Partnership to immediately and urgently eliminate child and forced labour from the cobalt value chain² through on-ground monitoring and third-party assessments.

In all my time in the Congo, I never saw or heard of any activities linked to either of these coalitions, let alone anything that resembled corporate commitments to international human rights standards, third-party audits, or zero-tolerance policies on forced and child labor. On the contrary, across twenty-one years of research into slavery and child labor, I have never seen more extreme predation for profit than I witnessed at the bottom of global cobalt supply chains. The titanic companies that sell products containing Congolese cobalt are worth trillions, yet the people who dig their cobalt out of the ground eke out a base existence characterized by extreme poverty and immense suffering. They exist at the edge of human life in an environment that is treated like a toxic dumping ground by foreign mining companies. Millions of trees have been clear-cut, dozens of villages razed, rivers and air polluted, and arable land destroyed. Our daily lives are powered by a human and environmental catastrophe in the Congo.

Although the scale of destruction caused by cobalt mining in the name of renewable energy is without contemporary parallel, the contradictory nature of mining is nothing new. Some of the most transformative advancements in human civilization would not have been possible without gouging the earth for minerals and metals. The revolution began around seven thousand years ago when people first applied fire to mined materials. Metals were melted and formed into objects used for commerce, adornment, and weapons. Tin was discovered five thousand years ago and mixed with copper to make bronze, the first alloy harder than its constituent metals. The Bronze Age was born, and the advent of metalworking sparked rapid advancements in human civilization. Bronze was used to fashion weapons, agricultural tools, and coins. The first forms of writing developed, the wheel was invented, and urban civilization evolved. It was also during the Bronze Age that cobalt was first used to color pottery. During the Iron Age, iron ore was mined and smelted into steel, which was used to fashion more powerful tools and weapons. Armies were built and empires were forged. During the early Middle Ages, Europeans created the first mining concessions. Governments offered commercial entities the rights to mine minerals from a parcel of land in exchange for a portion of revenues, a system that continues to this day.

Mining technology leaped forward during the late Middle Ages when miners started using black powder from China to blow up large rocks. The influx of mineral wealth from the New World, especially gold, financed much of the Renaissance, leading to the Industrial Revolution, which gave birth to the modern mining industry. Coal mining powered industrialization, and with it came a troubled history of environmental contamination, degradation of air quality, and exacerbation of climate change. The Industrial Revolution spurred further improvements in mining equipment—mechanical drills increased the efficiency of mining hard rock, and manual loading and hauling were replaced by electric conveyors, mine cars, and heavy-duty vehicles. These and other technological advancements allowed mining companies to dig deeper and more extensively than ever before.

By the late twentieth century, mining contributed to almost every aspect of modern life. Steel was used for buildings, homes, bridges, ships, trains, vehicles, and planes. Aluminum, tin, nickel, and other metals were used in thousands of industrial and consumer applications. Copper was used for electrical wiring and circuitry, military ordnance, and industrial machinery. Petroleum derivatives gave us plastics. Advancements in agricultural productivity would not have been possible without machinery from mined materials. Although today’s trillion-dollar global mining industry is dominated by coal, iron, bauxite, phosphate, gypsum, and copper, the so-called strategic and rare earth elements used in modern technology devices and renewable forms of energy are rapidly growing in economic and geopolitical importance. Many of these strategic minerals can be found in central Africa, chief among them cobalt.

Throughout much of history, mining operations relied on the exploitation of slaves and poor laborers to excavate ore from dirt. The downtrodden were forced to dig in hazardous conditions with little regard to their safety and for little to no compensation. Today, these laborers are assigned the quaint term artisanal miners, and they toil in a shadowy substrate of the global mining industry called artisanal and small-scale mining (ASM). Do not be fooled by the word artisanal into thinking that ASM involves pleasant mining activities conducted by skilled artisans. Artisanal miners use rudimentary tools and work in hazardous conditions to extract dozens of minerals and precious stones in more than eighty countries across the global south. Because ASM is almost entirely informal, artisanal miners rarely have formal agreements for wages and working conditions. There are usually no avenues to seek assistance for injuries or redress for abuse. Artisanal miners are almost always paid paltry wages on a piece-rate basis and must assume all risks of injury, illness, or death.

Although ASM is fraught with hazardous conditions, the sector has been growing rapidly. There are roughly forty-five million people around the world directly involved in ASM, which represents an astonishing 90 percent of the world’s total mining workforce. Despite the many advancements in machinery and techniques, the formal mining industry relies heavily on the hard labor of artisanal miners to boost production at minimal expense. The contributions from ASM are substantial, including 26 percent of the global supply of tantalum, 25 percent of tin and gold, 20 percent of diamonds, 80 percent of sapphires, and up to 30 percent of cobalt.³

To uncover the realities of cobalt mining in the Congo, I journeyed into the heart of the country’s two mining provinces—Haut-Katanga and Lualaba. I formed well-reasoned plans on how I would conduct my investigations, but few plans survive first contact with the Congo. Conditions were adversarial at every turn, including aggressive security forces, intense surveillance, the remoteness of many mining areas, distrust of outsiders, and the sheer scale of hundreds of thousands of people engaged in the feverish excavation of cobalt in medieval conditions. The journey into the mining provinces was at times a jarring time warp. The most advanced consumer electronic devices and electric vehicles in the world rely on a substance that is excavated by the blistered hands of peasants using picks, shovels, and rebar. Labor is valued by the penny, life hardly at all. There are many episodes in the history of the Congo that are bloodier than what is happening in the mining sector today, but none of these episodes ever involved so much suffering for so much profit linked so indispensably to the lives of billions of people around the world.

The field research for this book was conducted during trips to the Congo’s mining provinces in 2018, 2019, and 2021. Travel during 2020 was not possible due to the COVID-19 pandemic. As the pandemic wreaked havoc across the globe, its impact on the destitute people mining for cobalt remains largely unassessed. When industrial mines went into lockdown for extended periods during 2020 and 2021, demand for cobalt did not graciously hibernate. It only grew as people across the world relied more than ever on their rechargeable devices to continue working or attending school from home. The increased demand for cobalt pressured hundreds of thousands of Congolese peasants who could not survive without the dollar or two they earned each day to clamber into the ditches and tunnels, unprotected, to keep the cobalt flowing. COVID-19 spread rapidly in the artisanal mines of the Congo, where mask wearing and social distancing were impossible. The sick and dead infected by the disease were never counted, adding an unknown number to the industry’s bleak tally.

To obtain the testimonies included in this book, I devoted as much time as possible listening to the stories of those living and working in the mining provinces. Some spoke for themselves; others spoke for the dead. I followed institutional review board (IRB) protocols for human subject research during all my interviews with artisanal miners and other informants. These protocols are designed to protect sources from negative consequences for participating in research and include securing informed consent prior to conducting an interview, not recording any personal identifying information, and ensuring that any written or typed notes always remained in my possession. These procedures are especially important in the Congo, where the dangers of speaking to outsiders cannot be overstated. Most artisanal miners and their family members did not want to speak with me for fear of violent reprisals.

My investigations in the DRC were only made possible with the assistance of several guides and translators who were trusted in local communities. These guides assisted me in gaining access to scores of mining sites, as well as the people who toiled at them. Every one of the guides who worked with me did so at considerable personal risk. The Congolese government has historically gone to great lengths to obscure conditions in the mining provinces. Anyone seeking to expose the realities, such as journalists, NGO workers, researchers, or foreign news media, is heavily monitored during their stay. The Congolese military and other security forces are omnipresent in mining areas, making access to mining sites dangerous and at times impossible. Perceived troublemakers can be arrested, tortured, or worse. Out of an abundance of caution, I have used pseudonyms for my guides and the brave individuals whose testimonies are included in this book. I have also limited any personal descriptions or information that could be used to identify these individuals, as such information would place them and their families in jeopardy.

The severity of harm being caused by cobalt mining is sadly not a new experience for the people of the Congo. Centuries of European slave trading beginning in the early 1500s caused irreparable injury to the native population, culminating in colonization by King Leopold II, who set the table for the exploitation that continues to this day. The descriptions of Leopold’s regime remain disturbingly applicable to the modern Congo.

Joseph Conrad immortalized the evil of Leopold’s Congo Free State in Heart of Darkness (1899) with four words—The horror! The horror! He subsequently described the Congo Free State as the vilest scramble for loot that ever disfigured the history of human conscience and a land in which ruthless, systematic cruelty towards the blacks is the basis of administration. The year after Heart of Darkness was published, the first known person to walk the length of Africa from the Cape to Cairo, E. S. Grogan, described Leopold’s territory as a vampire growth. In The Casement Report (1904), Roger Casement, British consul to the Congo Free State, described the colony as a veritable hell on earth. Casement’s indefatigable ally in bringing an end to Leopold’s regime, E. D. Morel, wrote that the Congo Free State was a perfected system of oppression, accompanied by unimaginable barbarities and responsible for the vast destruction of human life.⁴

Every one of these descriptions equally conveys conditions in the cobalt mining provinces today. Spend a short time watching the filth-caked children of the Katanga region scrounge at the earth for cobalt, and you would be unable to determine whether they were working for the benefit of Leopold or a tech company.

Although the people of the Congo have suffered through centuries of exploitation, there was a moment—a fleeting flash of light at the dawn of independence in 1960—when the direction of the nation could have drastically shifted. The country’s first democratically elected prime minister, Patrice Lumumba, offered the nation a glimpse of a future in which the Congolese people could determine their own fates, use the nation’s resources for the benefit of the masses, and reject the interference of foreign powers that sought to continue exploiting the country’s resources. It was a bold, anti-colonial vision that could have altered the course of history in the Congo and across Africa. In short order, Belgium, the United Nations, the United States, and the neocolonial interests they represented rejected Lumumba’s vision, conspired to assassinate him, and propped up a violent dictator, Joseph Mobutu, in his place. For thirty-two years, Mobutu supported the Western agenda, kept Katanga’s minerals flowing in their direction, and enriched himself just as egregiously as the colonizers who came before him.

Of all the tragedies that have afflicted the Congo, perhaps the greatest of all is the fact that the suffering taking place in the mining provinces today is entirely preventable. But why fix a problem if no one thinks it exists? Most people do not know what is happening in the cobalt mines of the Congo, because the realities are hidden behind numerous layers of multinational supply chains that serve to erode accountability. By the time one traces the chain from the child slogging in the cobalt mine to the rechargeable gadgets and cars sold to consumers around the world, the links have been misdirected beyond recognition, like a con man running a shell game.

This system of obfuscating the severity of exploitation of poor people of color at the bottom of global supply chains goes back centuries. Few people sitting for breakfast in England in the 1700s knew that their tea was sweetened by sugar harvested under brutal conditions by African slaves toiling in the West Indies. The slaves remained far removed from the British breakfast table until a band of abolitionists placed the true picture of slavery directly in front of the English people. Stakeholders fought to maintain the system. They told the British public not to trust what they were told. They espoused the great humanity of the slave trade—Africans were not suffering, they were being saved from the savagery of the dark continent. They argued that Africans worked in pleasing conditions on the islands. When those arguments failed, the slavers claimed they made changes that remedied the offenses taking place on the plantations. After all, who was going to go all the way to the West Indies and prove otherwise, and even if they did, who would believe them?

The truth, however, was this—but for the demand for sugar and the immense profits accrued through the sale of it, the entire slavery-for-sugar economy would not have existed. Furthermore, the inevitable outcome of stripping humans of their dignity, security, wages, and freedom can only be a system that results in the complete dehumanization of the people exploited at the bottom of the chain.

Today’s tech barons will tell you a similar tale about cobalt. They will tell you that they uphold international human rights norms and that their particular supply chains are clean. They will assure you that conditions are not as bad as they seem and that they are bringing commerce, wages, education, and development to the poorest people of Africa (saving them). They will also assure you that they have implemented changes to remedy the problems on the ground, at least at the mines from which they say they buy cobalt. After all, who is going to go all the way to the Congo and prove otherwise, and even if they did, who would believe them?

The truth, however, is this—but for their demand for cobalt and the immense profits they accrue through the sale of smartphones, tablets, laptops, and electric vehicles, the entire blood-for-cobalt economy would not exist. Furthermore, the inevitable outcome of a lawless scramble for cobalt in an impoverished and war-torn country can only be the complete dehumanization of the people exploited at the bottom of the chain.

So much time has passed; so little has changed.

Although conditions for the Congo’s cobalt miners remain exceedingly bleak, there is nevertheless cause to be hopeful. Awareness of their plight is growing and, with it, hope that their voices will no longer call out into an abyss but into the hearts of the people at the other end of the chain, who are able to see at last that the blood-caked corpse of that child lying in the dirt is one of their own.

Unspeakable Richness

It is in every aspect an enormous and atrocious lie in action. If it were not rather appalling the cool completeness would be amusing.

—Joseph Conrad, letter to Roger Casement, December 17, 1903

WE ARE ALL AWARE of just how much today’s world depends on fossil fuels. Oil, coal, and natural gas are extracted in every corner of the globe, beneath oceans, deserts, mountains, and land. Imagine for a moment if almost three-fourths of all fossil fuel beneath the earth’s surface was instead extracted from a single patch of earth roughly four hundred by one hundred kilometers in size. Imagine that within this patch of earth, approximately half the oil was located in and around a single city and that the deposits were shallow enough for anyone to access with a shovel. This would surely be the most indispensable city in the world. Massive drilling companies would flock to it to stake their claims on the riches. So too would the local population from miles around. Violence would erupt to secure control of valuable territory. Preservation of the environment would become an afterthought. Regional governance would be marred by corruption. Profits would be asymmetrically distributed, with powerful stakeholders at the top of the chain accruing the most benefit while the local inhabitants languished. This is the exact situation taking place today with a crucial mineral that will be as important to our future as fossil fuels have been to our past. The mineral is cobalt, and the city is Kolwezi.

Kolwezi is tucked in the hazy hills of the southeastern corner of the Democratic Republic of the Congo. Although most people have never heard of Kolwezi, billions of people could not conduct their daily lives without this city. The batteries in almost every smartphone, tablet, laptop, and electric vehicle made today cannot recharge without Kolwezi. The cobalt found in the dirt here provides maximum stability and energy density to rechargeable batteries, allowing them to hold more charge and operate safely for longer periods. Remove cobalt from the battery, and you will have to plug in your smartphone or electric vehicle much more often, and before long, the batteries may very well catch on fire. There is no known deposit of cobalt-containing ore anywhere in the world that is larger, more accessible, and higher grade than the cobalt under Kolwezi.

Cobalt is typically found in nature bound to copper, and the copper-cobalt deposits in the Congo stretch in varying degrees of density and grade along a four-hundred-kilometer crescent from Kolwezi to northern Zambia, forming an area called the Central African Copper Belt. The Copper Belt is a metallogenic wonder that contains vast mineral riches, including 10 percent of the world’s copper and about half the world’s cobalt reserves. In 2021, a total of 111,750 tons of cobalt representing 72 percent of the global supply was mined in the DRC, a contribution that is expected to increase as demand from consumer-facing technology companies and electric vehicle manufacturers grows each year.¹ One might reasonably expect Kolwezi to be a boom town in which fortunes are made by intrepid prospectors. Nothing could be further from the truth. Kolwezi, like the rest of the Congolese Copper Belt, is a land scarred by the mad scramble to feed cobalt up the chain into the hands of consumers across the globe. The scale of destruction is enormous, and the magnitude of suffering is incalculable. Kolwezi is the new heart of darkness, a tormented heir to those Congolese atrocities that came before—colonization, wars, and generations of
