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

Copper Tailing an overview ScienceDirect Topics

Copper tailings are a finely ground waste after copper mineral has been extracted from the ores during beneficiation Similar to CS, the use of copper tailings as a geotechnical material has also been reported in the literature, but on a relatively smaller scale Collins and Ciesielski, 1994 Gupta and Thomas, 2013 Nitish et al , 2013 Miller
