Copper Mining and Processing: Processing of Copper Ores

Copper processing is a complied process that begins with mining of the ore ( less than 1% copper) and ends with sheets of 99.99% pure copper called hodes, which will ultimately be made into products for everyday . It is estimated that such recycling supplies 50% of copper used in the copper industry (Scott, 2011).
