Chemistry Tutorial : Electrowinning Copper

Chemistry Tutorial : Electrowinning Copper

Electrowinning Copper. In the electrowinning stage of copper extraction, the solution containing the copper ions is pumped through a series of tanks. Suspended in these tanks are sheets of lead alloy (anodes) alternating with cathodes made of either thin copper starter sheets or stainless steel blanks.

Electrowinning - Wikipedia

Electrowinning - Wikipedia

Electrowinning is the oldest industrial electrolytic process. The English chemist Humphry Davy obtained sodium metal in elemental form for the first time in 1807 by the electrolysis of molten sodium hydroxide. Electrorefining of copper was first demonstrated experimentally by Maximilian, Duke of Leuchtenberg in 1883.

The electrowinning of copper requires considerably more electrical energy than does the electrorefining process - an average of about 8 MJ/kg for electrowinning vs about 1.5 MJ/kg for electrorefining. In electrowinning the copper must be reduced from the cupric form to metal; whereas, in electrorefining the copper is already in metallic form .
