2017-11-1 1. Introduction. The effect of iron in copper electrowinning solution in hydrometallurgy SX-EW processing is well known. If the iron concentration in copper electrowinning solution increases, it reduces the current efficiency, increases the energy consumption and changes the surface morphology of cathodic copper, and these effects are intensified by increasing the flow

The term copper smelting designates the operations of melting the concentrate and extracting the copper by heat, flux, and the addition of oxygen. Copper concentrate is a mixture of the sulfides of copper, copper—iron, and iron with smaller amounts of gangue minerals. It normally contains 25—35% copper. [Pg.197]
