Once it’s located within the earth, copper ore goes through eight stages before the consumer sees it in various products that affect every day life in the home and business. Air is blown into the liquid matte forming blister copper, so called because the gas bubbles trapped in the solid form blisters on the surface. It is also the oldest metal known to man and was first discovered and used about 10,000 years ago. The flow diagram below shows how the percentage of copper increases as the ore is refined, first physically by froth flotation, then chemically by smelting and finally electrolytic refining. Mining for Copper Bearing Ore There are two categories of copper ore; sulphide ore which is processed to enrich it before smelting, and oxide ore that is subjected to acid treatment. We can illustrate the types of process using the example of chalcopyrite – CuFeS 2.From the formula, it is clear that iron and sulfur have to be removed in order to produce copper. The holes are filled with an explosive compound of fuel oil and ammonium nitrate which blasts thousands of tons of ore in a single detonation. 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 processing facilities are usually located near mining or extraction sites.
