Copper Life Cycle. From its original home in the earth’s crust, copper passes through several stages to reach a long life in essential products like electronics, appliances, electrical grids, vehicles and renewable energy technologies. As a 100% recyclable material, copper can be reused over and over again with no loss to its physical properties.

Secondary Smelting, Refining & Alloying of Copper
Refining Process Of Copper Sheets. In electrorefining, the copper anodes are loaded into electrolytic cells and interspaced with copper starting sheets, or cathodes, in a bath of copper sulphate solution.When a direct current is passed through the cell the copper is dissolved from the anode, transported through the electrolyte and re-deposited on the cathode starting sheets.
