Copper mining: the commonest ore used in the extraction of copper is chalcopyrite cufes 2 also known as copper pyrites and other such sulphides. the percentage of copper in the actual ore is too low for direct extraction of copper to be viable. the concentration of ore is required and it is done by the froth flotation method. concentration of flotation.
The flotation process. until quite recently copper ore had to be hand-picked if the extraction of the metal was to be economical. in fact, in the last century, ores of 4 percent grade were regarded as almost valueless. today such ores which would be regarded as relatively rich in copper are scarce; the great majority of mines contain the flotation.Hydrometallurgical 2 copper production. tables 6-1 and 6-2 provide capsule summaries of these processes. 1 pyrometaiiurgy is the extraction of metai from ores and concen-trates using chemical reactions at high temperatures. 2 hydrometallurgy is the recovery of metais from ores using water-based solutions. as early as 6000 b. c., native copper flotation.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 flotation.
