What are Clean Copper Concentrates?

Copper concentrate is the raw material for all copper smelters, which by processing it obtains an impure form of metallic copper, anode or blister copper, which is later used to produce high purity refined copper.

Clean copper concentrate is the concentrate after removing and/or normalizing impurities such as arsenic, antimony, and other penalty elements.
