Electrolytic refining is a process used to purify metals like copper. It involves using electricity to remove impurities from the metal. In the case of copper, impure copper is dissolved in an electrolyte solution, and when an electric current is applied, pure copper is deposited on the cathode. This process helps create high-quality, pure ...

1. Introduction. Copper anode slime is the byproduct of electro-refining of copper, which often contains precious metals and is a valuable secondary resource for recovering valuable products, such as silver, from it (Ding et al., 2017, Wang et al., 2017, Yldrm et al., 2014).The predominant method for silver recovery from anode slime is …
Location. birmingham. Dec 20, 2021. #7. Running copper electrolytic cells is one of the oldest technologies around so there is plenty of information as to how to run one successfully, in fact at one point the copper refiners in the US produced a large percentage of the silver there and quite an amount of gold. S.

The synthetic fibre industry has found an application for it in the production of their raw material. The metal industry uses large quantities of copper sulphate as an electrolyte in copper refining, for copper coating steel wire prior to wire drawing and in various copper plating processes. The mining industry employs it as an activator in the ...
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 as the cathode. In this setup, an electrolyte (metal salt aqueous solution ...

The copper(II) ions are removed again from the organic solvent by reaction with fresh sulphuric acid, producing a much more concentrated copper(II) sulphate solution than before. Electrolysis of the new solution. Copper(II) ions are deposited as copper on the cathode (for the electrode equation, see under the purification of copper below).

If the copper to be refined is an alloy of copper plus some less electronegative metals, like zinc, both metals are oxidized and dissolved at the anode. But only copper is reduced at the cathode. So the solution contains more and more zinc. As a consequence, it contains less and less copper. And the solution becomes less and less …
The conventional treatment of copper–gold concentrates involves smelting, converting and electro-refining to produce a copper-cathode product. Sulfur in the copper concentrates is oxidized to sulfur dioxide during smelting and converting and is normally used to make by-product sulfuric acid. Iron in the copper concentrates reports to the …
