Continuous melting and refining of secondary and/or blister copper |
摘要 |
Disclosed is an integrated system for continuously melting and refining secondary and blister copper to produce and continuously cast anode grade copper comprising: continuous melting of secondary and blister copper in an optional fuel vertical shaft furnace; continuously or semicontinuously skimming initial slag from the surface of the melted copper in a slag vessel as it drains from the shaft furnace; collecting a reservoir of molten copper in a holding furnace capable of controlling its temperature and subsequent flow; adding fluxes to the molten copper; directing the molten copper into an oxidation vessel where the molten copper and impurities are oxidized; transferring the oxidized and fluxed molten copper to a second slag vessel where slag is skimmed from its surface; flowing the oxygen rich molten copper into a reduction vessel where oxygen content is reduced; collecting a supply of refined molten copper in a final holding vessel; continuously passing the refined molten copper through a filtering ladle containing ceramic foam molten copper filters; and continuously supplying refined and filtered molten copper to a casting ladle which continuously casts the refined and filtered molten copper into anodes of suitable quality for electrorefining or into a cast product not requiring electrorefining.
