Corral Quemado is a closed manganese mine in Coquimbo Region, in north-central Chile. It was last active in 2009 when the company Manganesos Atacama ceased operations and manganese mining in Chile ended.[1][2] The mine was particularly active in the 1940s when it was notorious for its poor labour conditions including child labour.[3] Work conditions in the mines denounced by members of the National Congress of Chile in 1943 and 1944.[3] Manganese ore in the mine appears in the form of near-horizontal sheets of a thickness ranging from one to two meters.[3] Some mine workers developed a disease known as locura mangánica (lit. "manganic madness") due to exposure to manganse.[3]
