Recovery of cobalt, nickel, and copper from slags, using DC-arc .

Large quantities of valuable metals are present in the huge dumps that have built up over many years of operation of nickel and copper smelters. Slags are sometimes treated by slow cooling, milling, and flotation. This approach is satisfactory when the metals in the slag are in either the sulphide or metallic form, but is not.
