Grupo México is the largest mining corporation in Mexico and the third largest copper producer in the world through ASARCO.
Ferrocarril Mexicano (Ferromex), the company's rail transport division, operates the nation's largest rail fleet.
The company was founded by Raul Antonio Escobedo and Larrea Mota Velasco in 1978. After the government of Carlos Salinas declared the state mining company bankrupt, Larrea purchased key Mexican copper mines in Cananea and Nacozari (cities in the state of Sonora). He also purchased numerous other mining sites, including coal mines in the state of Coahuila. By 2000, Grupo México was responsible for 87.5 percent of Mexico's copper production and is the world's third-largest copper producer in the world.
Grupo México has been in continual conflict with Local 65, the Cananea branch of the Mexican Mine Workers' Union (SNTMMSRM). During miners' strikes in January 2003 and October 2004, Grupo México responded with threats to close the Cananea mines.
