... valuable impurities from the copper for subsequent recovery as by-products. This process is the basis of purification of pyrometallurgical copper, which is used as the anode. The impure copper is cast in the shape of anodes approximately 1.0 × 1.0 × 0.05 m (40 × 40 × 2 in.) weighing 300 to 400 kg (660...

... of the chemical partitioning between the slag and the weld metal ( Ref 3 , 7 ). This dependence suggests that the pyrometallurgical reactions involved are influenced by the processes that occur at the electrode tip. As a specific example, the welding parameters affect metal-droplet size, which in turn alters...
