Electrolytic Refining Meaning, Electrorefining of Copper

Electrolytic refining is a process of refining a metal (mainly copper) by the process of electrolysis. As far as the mechanism of the process is concerned, during electrolysis, a large chunk or slab of impure metal is used as the anode with a thin strip of pure metal at the cathode. In this setup, an electrolyte (metal salt aqueous solution) depending on the metal is often used.

ELECTROLYTIC REFINING OF COPPER NROER

ELECTROLYTIC REFINING OF COPPER Electrolyte Impure Copper Antimony Selenium Tellurium Silver Gold Platinum ELECTROLYTIC REFINING The process of electrolytic refining is used to purify impure metals. In this process, the impure metal is made anode and a thin strip of pure metal is made cathode. A solution of the salt of the metal, which is to be refined is used as an electrolyte. On passing

Electrolytic Copper Business Sumitomo Metal Mining Co

SMM manufactures electrolytic copper by refining copper concentrate mainly imported from South American countries in flash furnaces in the Toyo Smelter & Refinery, which is refined to 99.99% purity or higher after going through the converter, refining furnace, and electrolytic plant. Since our electrolytic copper is superior in electric conductivity and workability, it can be used for a wide

Copper Refining an overview ScienceDirect Topics

It should be noted that all electrolytic processes occur in a liquid electrolyte which can be an aqueous solution containing an appropriate supporting electrolyte, such as H 2 SO 4 + CuSO 4 for copper refining, and H 2 SO 4 + NiSO 4 for nickel extraction, or a molten salt at elevated temperatures, for example, the molten mixture of Na 3 AlF 6 (cryolite), AlF 3 and Al 2 O 3 for aluminium

12.3 Primary Copper Smelting

Electrolytic refining separates copper from impurities by electrolysis in a solution containing copper sulfate (Cu2SO4) and sulfuric acid (H2SO4). The copper anode is dissolved and deposited at the cathode. As the copper anode dissolves, metallic impurities precipitate and form a sludge. Cathode copper, 99.95 to 99.96 percent pure, is then cast into bars, ingots, or slabs.
