Copper is an essential plant nutrient, classified as a micronutrient. It has a role in various important processes in plants. For example: Copper is a structural element in numerous proteins Essential for the photosynthesis process - plastocyanin is a copper protein that acts as an electron carrier in the electron transport chain of photosynthesis.

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.
