chemicals of producing copper through mining

At this stage of the process the chemical reactions begin They convert the copper minerals into copper metal We can illustrate the types of process using the example of chalcopyrite - CuFeS 2 From the formula it is clear that iron and sulphur have to be removed in order to produce copper The U S mining industry consists of the search for extraction beneficiation and processing of naturally occurring solid minerals from the earth These mined minerals include coal metals such as iron copper or zinc and industrial minerals such as potash limestone and other crushed rocks Oil and natural gas extraction (NAICS code 211) is not included in this industry

Top Copper Producing Countries In The World

Apr 25 2017Mining operations extract copper from the ground via open pit mines Once the copper-containing earth is extracted the extract is ground to fine ore and put through a froth flotation process This process combines the ore with water and a collector chemical that makes copper hydrophobic (a condition which repels water)
