Electrowinning Copper Chemistry Tutorial

Electrowinning Copper Key Concepts. Electrowinning refers to the process of using electrolysis to extract a metallic element from the compounds in its ore. Copper occurs on Earth both as native copper (the uncombined element, Cu), and in ores (copper compounds, or mixtures of compounds, from which copper metal can be extracted profitably).

Understanding Impurities in copper electrometallurgy

Copper electrorefining occurs after the pyrometallurical processing of ores not amenable to acid leaching. The process produces high purity copper either by plating on a re-usable stainless cathode or a copper starter sheet. Copper starter sheets are produced during a 21-hour plating cycle, using titanium sheet cathodes, which are likewise ...
