More Details Extraction Of Copper From Copper Ore,Metallurgy - Purification of ores,The purification of ore means removal of gangue from the powdered ore. This process is otherwise called concentration of the ore or ore dressing. Thus, the percentage of the ore in the concentrated ore is higher than that in the original ore. The purification or concentration of ore can be brought about in the following ways, depending upon the type of ore. (i) Gravity separation process or,

29/03/2017· KAZ Minerals presentsCopper is one of the top seven metals known since the ancient time. Actually, humankind knows over 170 copper-containing minerals. Coppe...Copper Mining and Extraction Sulfide Ores,These produce many millions of tonnes of copper ore per year. The main ores of copper are sulfides and oxides. From their chemical formulas you can calculate the percentage of copper in each mineral. However this is not the same as the percentage of copper in the ore as that also contains unwanted silicates and other minerals, called gangue, that will have to be separated.
