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 cathodeThe process for electrorefining copper is typical of those carried out in aqueous solution The electrolyte is copper sulfate (07 molar) and sulfuric acid (2 molar) and the way in which the purification of the copper occurs can be seen by considering the metals likely to be found as impurities :Electrorefining of CopperThe 99% pure copper from the anode furnace is cast into 750pound, 3inch thick, rectangular slabs called anodes The final step is a process called electrorefining is done by electrolysis where the copper anodes from the smelterCopper Electrorefining Last step Elmhurst UniversityElectrolytic refining (electrorefining) is a process used to make impure copper pure Unlike aluminum, copper metal is fairly easy to obtain chemically from its ores By electrolysis, it can be refined and made very pure—up to 99999%Copper Purification Process Electrolytic Copper Refining Table of ContentsApparatus and Experimental TechniquesRotating Electrode CellsSingle Channel CellsMultichannel CellResultsRotating Electrode CellsRing ElectrodesCylinder ElectrodesSingleChannel CellSynthetic Electrolyte TestsTankhouse Electrolyte TestsComparison with Industrial Refining CellsMultichannel CellInitial Electrolysis StudiesFiltration and Settling of Anode SludgeOperational Electrorefining Copper Metallurgist Mineral Processing
