How To Clean Peacock Ore? | Cleanestor

Bornite is an important ore mineral because it contains nearly 63% Copper when pure. However, it rarely occurs naturally as pure bornite; it usually contains some Chalcopyrite which lowers the overall Copper content to around 30%. This means that bornite must be concentrated before it can be processed into Copper metal or ore compounds.
