- Beneficiation Of Copper Ore From D R Congo
This culminates into low grade, fine grain size, complex ore mineralogy, and poor liberation, thus, causing the beneficiation of lead-zinc ore a challenging task. This paper summarizes the classification of ore deposits and different beneficiation techniques that are currently employed for the treatment of lead-zinc ore.

The beneficiation of high talc-containing copper–cobalt flotation tailings was studied by centrifugal gravity concentration. It was found that copper and cobalt minerals were finely disseminated in the gangue matrix so that conventional gravity concentration using spirals and shaking tables would be ineffective.

Copper - From Beginning to End. Copper is a major metal and an essential element used by man. It is found in ore deposits around the world. It is also the oldest metal known to man and was first discovered and used about 10,000 years ago. And as alloyed in bronze (copper-tin alloy) about 3000 BC, was the first engineering material known to man.

Addition of copper sulfate at pH values ranging from 7 to 10 may slow down floatability of iron sulfides. Excessive addition of copper sulfide may result in lower recovery due to oxidation of xanthate into dixanthogen in solution, thus reducing the effectiveness of collection. Copper sulfate addition also appears to impact froth stability.
