FIELD: metallurgy. SUBSTANCE: method includes antimony and lead leaching from copper anode slime in a solution containing 50-200 g/dm 3 of glycerin, 50-100 g/dm 3 of alkali and a reducing agent, in an amount that provides the system oxidation-reduction potential more positively than +0.8 V at a temperature of 70-90°C for 2-3 hours. Thus lead from the leach solution is educed by known methods.

Electrowinning - Wikipedia

Electrowinning, also called electroextraction, is the electrodeposition of metals from their ores that have been put in solution via a process commonly referred to as leaching. Electrorefining uses a similar process to remove impurities from a metal. Both processes use electroplating on a large scale and are important techniques for the economical and straightforward purification of non ...
