REFINING OF BLISTER COPPER-ORE-GANGUE-USES OF LEAD

Blister copper is refined by an electrolytic process. Blister copper in the form of a large plate is made as anode. A thin plate of pure copper is cathode. A solution of CuSO 4 is used as an electrolyte. The impure blister copper dissolves at the anode.Copper extraction - Wikipedia,The blister copper is put into an anode furnace, a furnace that refines the blister copper to anode-grade copper in two stages by removing most of the remaining sulfur and iron, and then removing oxygen introduced during the first stage.Refining of blister copper - [email protected],Refining of blister copper U.

In fire refining, molten blister copper is placed in a fire-refining furnace, a flux may be added, and air is blown through the molten,Definitions - International Copper Study Group,Blister copper consists of an impure form of copper produced by blowing air through molten copper matte. During the conversion process, sulphur, iron and other impurities are oxidised. The copper content is normally about 98 % by weight. It is the product of a converting furnace. Copper anodes for electrolytic refining: Copper partly refined by complete fusion is cast into anodes for further refining
