Cobalt Life Cycle

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.
