Abstract

The invention discloses a production technology of refined copper. The technology comprises the following steps: selecting copper concentrate; continuously feeding the produced molten matte into a converter; converting to obtain coarse copper; arranging electrolytic baths; arranging linings of the electrolytic baths; connecting the electrolytic baths in series in a copper electrolyzing workshop; arranging an anode plate, a cathode plate and an electricity conducting rod; charging direct current to the electrolytic baths; dissolving copper in a Cu<2+> form under the effect of the direct currentafter electrons on an anode are lost; dissolving out the Cu<2+> in a copper metal form after electrons are supplied to a cathode; recovering anode slime containing precious metal, selenium, telluriumand other rare metals as a byproduct in copper electrolyzing; extracting and cleaning base metal impurities which gradually accumulate in electrolyte in regular period; removing copper sheets from the baths; and washing the copper sheets with water. According to the production technology of the refined copper, the processes are compact; the refined copper smelting efficiency is improved; and moreover, the energy consumption is reduced.

Description

technical field [0001] The invention relates to the technical field of metal copper smelting, in particular to a refined copper production process. Background technique [0002] In the electrical industry, the purity requirements for copper are very high. Therefore, almost all blister copper in modern times has been refined to remove impurities. In the electrolytic refining of copper, pure copper sheets are used as cathode sheets, which are placed in electrolytic cells alternately and treated with sulfuric acid. The aqueous solution of copper and sulfuric acid is used as the electrolyte. Under the action of direct current, the copper on the anode and the base metal with a relatively negative potential dissolve into the solution, while the noble metal and some metals (such as selenium and tellurium) are insoluble, and become anode sludge and sink in electrolysis. tank bottom. The existing smelting process has a large site and serious waste of energy. Therefore, the present i...
