Copper processing is a complicated process that begins with mining of the ore (less than 1% copper) and ends with sheets of 9999% pure copper called cathodes, which will ultimately be made into products for everyday useThe most common types of ore, copper oxide and copper sulfide, undergo two different processes, hydrometallurgy and pyrometallurgy, respectively, ,
FROTH FLOTATION “So many variables influence flotation that it will be long before every one of them can be investigated and its influence on the process determined” The froth flotation process was patented by E LSulman, H F K Pickard, and John Ballot in 1906, 19 years after the first cyanide process patents of MacArthur and the Forests
