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.

Processing of the Kipushi Cu–Zn sulphide ore started in 1935. Initially, the plant treated about 20,000 tonnes of ore per month using a single flotation circuit with conventional reagents such as xanthates and pine oil. Over the period 1937 to 1940, the concentrator was extended to allow the differential flotation of Cu–Zn.
