Cobalt is mined across the world and the vast majority is produced as a by-product from large scale copper and nickel mines. The process of cobalt mining involves many steps, including locating suitable deposits and extracting the ore before refining it into a usable form. Cobalt is only extracted alone in Morocco and some Canadian arsenide ores.

Metallic sulfide mining (aka hard rock mining) is the practice of extracting metals such as nickel, gold and copper from a sulfide-rich ore body. Sulfides are a geologic byproduct of mining in this area, and by exposing sulfides to the air and water in our atmosphere, sulfuric acid can be created — threatening to poison the nearby water ...
Pure copper metal is generally produced from a multistage process, beginning with the mining and concentrating of low-grade ores containing copper sulfide minerals, and followed by …
