Electrolytic copper refining cell
WebIn the electrolytic process, copper is electrodeposed to obtain a spongy powder deposit at the cathode rather than a smooth, adherent one. In this feature, it differs from the process of copper refining where a strongly adherent product is desired. Low copper ion concentration and high acid content in the electrolyte favor formation of powder deposits. WebIn metallurgy, electrolytic cells are used in the electrorefining of many non-ferrous metals, producing highly pure metals such as lead, zinc, aluminium, and copper. Electrolytic cells are used in the electrowinning of these metals. It is used to extract pure sodium metal from molten sodium chloride by keeping it in an electrolytic cell ...
