Copper mining. From ore to copper. About 80 of all copper extracted comes from sulphide ores. A typical ore contains only 0.5 to 2.0 copper. It is a measure of the value of copper that it is worth extracting it from such small concentrations. The ore is a mixture of minerals and rock called gangue. The most common copper minerals are

However copper ore is a finite resource and it makes sense to conserve ore by recycling. It is cheaper to recycle old copper than to mine and extract new copper. Recycled copper is worth up to 90 of the cost of the original copper. Recycling helps to keep the cost of copper products down.

Leaching is the process to extract pure copper from a low grade ore. Leaching is the process of extracting substances from a solid by dissolving them in a liquid, in this process the ore is dissolved in liquid but not impurities. Then the copper solution is reacted with iron to get pure copper reduction process. Cu2 H2 Cupure 2H
