Copper Mining and Processing Processing of 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 due to the different

Mining and Mineral Use Earth Science

Copper is mined and extracted from copper ores To extract the metal from the ore the rock is melted at a temperature greater than 900 176 C which requires a lot of energy Extracting metal from rock is so energy intensive that if you recycle just 40 aluminum cans you will save the
