mining cobalt from copper

Cobalt Mining - Cobalt Institute

Cobalt Mining Cobalt is mined across the world and the vast majority is produced as a by-product from large scale copper and nickel mines. Cobalt is only extracted alone in Morocco and some Canadian arsenide ores. 98% of cobalt production is mined as a by-product Technologies include both underground and surface mining. Various nickel and []

Cobalt Mining in the Democratic Republic of Congo -

The majority (around 65-85%) of all cobalt mined in the DRC comes from large scale copper mines that are mostly operated by large multinational mining companies. The operations in these mines are strictly controlled by the operators and local governments. The remaining 15-35% comes from artisanal and small-scale mining (ASM).
