Serra dos Carajás

mountains, Brazil
Also known as: Carajás Mountains

Quick Summary

The Serra dos Carajás is a mountain range in Brazil known for its rich mineral deposits. It is one of the world's largest and most valuable sources of iron ore, and also yields gold, copper, nickel, manganese, tin, and bauxite. The exploitation of these resources, primarily by the company Vale, has been profitable but has also caused significant environmental damage. For example, mercury used in gold extraction has contaminated rivers and fish, posing health risks to local populations. The region's energy needs are met by the Tucuruí hydroelectric plant on the Tocantins River.1
