Copper Scrap Recycling-Metal Recycling- - Metalcess Refining improves the ductility of copper so that extremely fine wires can be drawn. It also shows the reduction process showing copper being reduced out of solution using electricity. A solution of a soluble salt of the same metal is taken as the electrolyte. The Copper Market, Treatment and Refining Charges The refining anodes taken out from the refining furnace is changed into electrolytic copper with purity of 99.99% through an electrolysis process: During electrolysis, copper (II) ions leave the impure copper anode and since they are positive, migrating to the negative cathode. Impurities increase the chance that the wire will break during the drawing process. These processes do not completely remove Ni and Sn from Cu, so the refining furnace product must be electrorefined. By electrolysis, it can be refined and made very pureup to 99.999%. The production of this molten copper is suitable to produce FRHC (Fire Refined High Conductivity) copper rod, strip, billets or copper ingot.
