C opper plate electrorefining (ER) is a process used in industry for refining copper. Copper is dissolved from the anode plate into solution and is plated onto the opposing cathode by means of the passage of current between the plates.

Abstract The energy saving potential and refining capability of three copper (I)/electrolyte systems for the electrorefining of copper were compared experimentally. The alternative electrolyte systems studied were copper (I)/acid chloride, copper (I)/acetonitrile and sulfuric acid, and copper (I)/ammonia solutions.

Abstract The impurities in copper anodes occur both in solid solution in the copper metal matrix and in discrete inclusions at the copper grain boundaries. During electrorefining, all the impurities undergo extensive chemical and/or morphological changes.

Copper has a very high per unit volume electrical conductivity. It can be easily drawn through strings, whether single or multi filament, which can be conveniently and regularly twisted without undue toughness of operation. Copper wire is readily tinned, has superior soldering properties and is resistant to corrosion at points of contact.

Copper from electrorefining, after melting and casting, contains less than 20 ppm impurities, plus oxygen which is controlled at 0.018–0.025%. Electrorefining entails electrochemically dissolving copper from impure copper anodes into an electrolyte containing CuSO 4 and H 2 SO 4 and then electrochemically depositing pure copper from the electrolyte onto stainless steel or copper …

Tests were confirmed that those anodes can be used in the commercial copper electrorefining process based on the fact that the elements from anodes were dissolved, the total anode passivation did not occur, and copper is deposited onto cathodes.

The 99% pure copper from the anode furnace is cast into 750-pound, 3-inch thick, rectangular slabs called anodes. The final step is a process called electrorefining. This is done by electrolysis where the copper anodes from the smelter become positive electrodes and thin, three-foot square sheets of pure copper are used as negative electrodes.

Electrolyte flows continuously in and out of the cells. The anodes begin to dissolve and pure copper begins to plate on the cathodes. Each anode is electrorefined until about 80%–85% of the mass has dissolved. Two or three cathode plating cycles are produced from a single anode. Each copper cathode typically weighs 50–160 kg. This multicathode plating cycle ensures that …

Electrolytic Copper Refining Tank: the anodes of impure copper are refined by electrolytic means to the pure cathode copper in the refining tank. It is filled with a solution of sulfuric acid and copper(II) sulfate, in which the anodes and cathodes are interleaved and immersed — between anodes are suspended starting sheets which are thin sheets of …

The aim of this work was to investigate the electrorefining process of copper anodes with increased Ni, Pb, Sn, and Sb content in comparison with the content of those elements in the commercial copper anode electrorefining process. The two types of copper anodes are proposed for testing regarding the Ni, Pb, Sn, and Sb content as the ingredients.

The composition of raw materials for copper pro- duction is constantly changing, which entails the need to improve the process of electrolytic refining (ER), the main purpose of which is to purify the metal from impurities. Copper anodes obtained after the fire refining of blister copper contain up to 1% of impuri- ties of metals and nonmetals.

Copper electrorefining is the most common method for the production of high-purity copper cathodes. In copper electrorefining, copper metal is dissolved from a copper anode to the electrolyte and deposited on the cathode using electricity.
