chemistry of copper processing

chemistry of copper processing 」

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
