Copper mining is the process of extracting copper ores from the earth, which are then processed to obtain the pure metal. This industry is a significant economic driver in many regions, especially in Latin America and the Caribbean, where abundant copper reserves contribute to local and national economies. The extraction and processing of copper have environmental and social …

High-purity copper is produced through a multi-step process. It begins with mining copper ores, which are then crushed and ground into fine particles. These particles undergo froth flotation to concentrate the copper minerals, resulting in a copper concentrate. The concentrate is smelted at high temperatures to produce a matte, which is further ...

Surface mining, which includes strip mining, open-pit mining, and mountaintop removal, removes soil and rock from on top of the mineral deposit. It may begin as soon as the pre-development steps are complete. Underground mining uses shafts and tunnels to access deeply-buried mineral deposits, while the overlying rock is left in place.
