Copper industrial minerals include: natural copper, chalcopyrite, chalcocite, tetrahedrite, azurite, malachite, etc. Chalcopyrite (a compound of copper, sulfur, and iron) is mined mainly, followed by chalcocite and bornite. If copper ore wants to be fully utilized, it must be processed by flotation. Flotation separation is an important copper ore beneficiation process in …
or further use. Manganese, an impurity often associated with these raw materials, can be precipitated as manganese oxide either together with iron or separately. From iron and manganese removal, the pregnant leach solution can be fed to solvent extraction or other solution purification stages such as ion exchange for further
Oxide manganese usually adopts washing and gravity separation solutions for beneficiation. Weathering-type manganese oxide ore often contains a large amount of mud and powder ore, so it needs to be washed by trommel washer …
