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, due to the different ...

Copper Mining and Extraction Copper Mining Processing

The process of recycling copper follows approximately the same steps as is used to extract copper, but requires fewer steps. High purity scrap copper is melted in a furnace and then abridged and cast into billets and ingots; lower cleanliness scrap is refined by electroplating in a bath of sulfuric acid.

Copper extraction - Wikipedia

Copper extraction refers to the methods used to obtain copper from its ores.The conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors.. As in all mining operations, the ore must usually be beneficiated (concentrated).
