Smelting, Refining and their Products. The product of flotation is called 'concentrate'. It is passed on to the smelter and, after further processing, refining is done in great batteries of electrolytic tanks.
Refining improves the ductility of copper so that extremely fine wires can be drawn. Impurities increase the chance that the wire will break during the drawing process.Copper conducts electricity Only silver conducts electricity better than copper, traditionally Silver cost 40 times the price of Copper.

The final product of the refining process is electrolytic tough pitch (ETP) copper normally containing between 99.94 and 99.96% Cu. Cathodes are remelted under controlled conditions and cast into forms suitable for further processing.
The end result of of the copper smelter operations is anode copper which is 99% pure (see graphic on the left). An example where copper is further purified is at the Asarco electrolytic plant in Amarillo, Texas. The 99% pure copper from the anode furnace is cast into 750pound, 3inch thick, rectangular slabs called anodes.
