About: Patio process

An Entity of Type: Election, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org

The patio process is a process for extracting silver from ore. Smelting, or refining, was necessary because silver does not occur by itself in a natural state like some metals. Instead, it is made up of a larger ore body. Thus, smelting, or refining, is necessary to remove other byproducts to get at pure silver. The process, which uses mercury amalgamation to recover silver from ore, was reportedly invented by Bartolomé de Medina in Pachuca, Mexico, in 1554. It replaced smelting as the primary method of extracting silver from ore at Spanish colonies in the Americas. Although some knowledge of amalgamation techniques were likely known since the classical era, it was in the New World that it was first used on a large industrial scale. Other amalgamation processes were later developed, import

dbo:abstract
  • En minería, el método de patios es un proceso para extraer plata de las menas del metal. El proceso fue inventado por Bartolomé de Medina en Pachuca, México, en 1554.​ Fue el primer proceso en utilizar la amalgamación con mercurio para recuperar la plata del mineral. Reemplazó a la fundición como el método principal para extraer plata del mineral en los virreinatos españoles en las Américas y en la propia península. Otros procesos de amalgamación se desarrollaron posteriormente, siendo destacables por su importancia el método de los cazos y su variante, el proceso Washoe. Los métodos utilizados para la separación de la plata generalmente diferían de los usados con el oro, aunque a veces también se usaba la amalgama con mercurio para extraer oro. (es)

Although some knowledge of amalgamation techniques were likely known since the classical era, it was in the New World that it was first used on a large industrial scale. Other amalgamation processes were later developed, importantly the pan amalgamation process, and its variant, the Washoe process. The silver separation process generally differed from gold parting and gold extraction, although amalgamation with mercury is also sometimes used to extract gold. While gold was often found in the Americas as a native metal or alloy, silver was often found as a compound such as silver chloride and silver sulphide, and therefore required mercury amalgamation for refinement.
