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.

Copper processing
Copper processing - Roasting, Smelting, Converting: Once a concentrate has been produced containing copper and other metals of value (such as gold and silver), the next step is to remove impurity elements. In older processes the concentrate, containing between 5 and 10 percent water, is first roasted in a cylindrical, refractory-lined furnace …
From Ore to Finished Product
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.

Copper Smelting Slideshow
Copper concentrate (CuFeS 2) is fed into the furnace along with a flux of silica sand, SiO 2, and oxygen, O 2. The flux is used to control the chemistry of the slag. In particular, it causes the iron (Fe) in the copper concentrate to accumulate in the slag phase, while the copper (Cu), accumulates in the matte phase. Copper Concentrate
