Recovery of cobalt, nickel, and copper from slags, using
When carbon is added to the slag, the various metallic elements reduce to different extents, at a given level of carbon addition. This behaviour allows a reasonable degree of separation to take place during smelting. The intention in this part of the process is to separate the valuable non ferrous metals from the iron and the gangue constituents present in the slag. Figure 3 illustrates the
