How To Extract Copper From Copper Ores

The percentage of copper in the actual ore is too low for direct extraction of copper to be viable. The concentration of ore is required and it is done by the Froth Flotation method. Concentration of Ore The ore is crushed into a fine powder and a suspension is created in water. To this are added, Collectors and Froth Stabilizers.

    Copper ores. An ore is a rock containing enough valuable mineral to make it worth extracting. In the case of copper, it is worth extracting when there is about 2 kg of copper per 1,000 kg of ore (0.2 ). Copper minerals are found in over one hundred varieties, although only a few have been worked for copper on a large scale.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.
