12.3 Primary Copper Smelting

2015-9-10  The copper anode is dissolved and deposited at the cathode. As the copper anode dissolves, metallic impurities precipitate and form a sludge. Cathode copper, 99.95 to 99.96 percent pure, is then cast into bars, ingots, or slabs. 12.3.3 Emissions And Controls Emissions from primary copper smelters are principally particulate matter and sulfur oxides

What Is a Process Furnace? - wiseGEEK

Blast furnaces are used to smelt and purify a wide variety of metals from iron to copper and gold. Induction furnaces use the principle of electrical induction produced by changes from high voltage to low voltage current as a heat source. They are widely used to melt and alloy a range of both ferrous iron and steel, and non-ferrous metals.
