Copper Production: How Is Copper Made? - ThoughtCo
Sep 26, 2019· Regardless of the ore type, mined copper ore must first be concentrated to remove gangue or unwanted materials embedded in the ore. The first step in this process is crushing and powdering ore in a ball or rod mill. Sulfide Copper Ores .Copper Mining and Processing: Processing Copper Ores,,Copper processing is a complicated process that begins with mining of the ore (less than 1% copper) and ends with sheets of 99.99% pure copper called cathodes, which will ultimately be made into products for everyday use.The most common types of ore, copper oxide and copper sulfide, undergo two different processes, hydrometallurgy and pyrometallurgy, respectively,INDONESIA | Freeport-McMoRan,Through its subsidiary, PT-FI, FCX mines one of the world’s largest copper and gold deposits in the Grasberg minerals district in Papua, Indonesia.
