Corral Quemado mine

Corral Quemado is a closed manganese mine in Coquimbo Region, in north-central Chile. It was las active in 2009 when the company Manganesos Atacama ceased operations and manganese mining in Chile ended. The mine was particularly active in the 1940s when it was notorious for its poor labour conditions including child labour. Work conditions in the mines denounced by members of the National Congress of Chile in 1943 and 1944. Manganese ore in the mine came in the form of near-horizontal sheets of a thickness of one or two meter. Some miners developed a disease known as locura mangánica due to exposure to manganse.
