Konkola Copper Mines (KCM) is the largest copper mining company in the country. Although based in Chingola, 15% of its operations—namely Nkana Refinery, Nkana Acid Plants and Nkana Smelter (the largest smelter in the nation) -- are located in Kitwe. The Nkana Smelter is the largest primary copper production plant in Zambia.

Copper is produced in the U. S. primarily by pyrometallurgical smelting methods. Pyrometallurgical techniques use heat to separate copper from copper sulfide ore concentrates. Process steps include mining, concentration, roasting, smelting, converting, and finally fire and electrolytic refining. 12.3.2 Process Description2-4

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.
