Sulfide ores are used to produce a matte (40 – 50 wt % Cu) and a disposal slag (ca. 0.5 wt % Cu). In contrast, oxide ores are processed directly to impure black copper ( 95 wt % Cu) and to a copper-rich slag. The two ore types can be smelted together to produce matte and a slag with low copper content. Another
