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.

The mine produced 270,724t of copper and 167,395oz of gold in 2013. An expansion at the mine is underway to increase the production capacity to 400,000t of copper by 2015. Northwest Rail Company (NWR), in cooperation with Grindrod, will construct a 290km long new railway line connecting Chingola to the Kansanshi, Lumwana and Kalumbila mines.

Copper processing begins with mining copper ore, which contains less than 1% of copper, and ends with sheets of 99.99% pure copper (cathodes). Copper mining generally takes place through open-pit mining, in which a series of stepped benches are dug deeper into the earth. Yet, it can also be mined underground, through horizontal tunnels.

The underground mining methods we use include room and pillar, narrow vein stoping and large-scale mechanised mining. Room and pillar mining is a style of mining where tunnels are driven in a chess board pattern with massive square pillars between them which are gradually cut away as the work proceeds. We use this for mining coal.
