purification of copper by electrolysis metal extraction

Copper can be extracted from copperrich ores by heating the ores in a furnace (smelting) and the copper can be purified by electrolysis. However, the supply of copperrich (high grade) ores is limited.

Method for Smelting Low-sulfur Copper Ores.

An improved method for smelting copper ores such as chalcocite (cu2s) is presented. The improvement involves the use of calcium sulfate and iron as smelting additives. Conventional smelting of such ores requires the addition of pyrite (fes2) or chalcopyrite (cufes2), both expensive and often not
