2018-8-1 · Copper exists in the slag in two distinct forms: oxide (Cu 2 O) and metal (Cu). As the Fe 3 O 4 content decreases, the oxygen potential of the slag also decreases. This leads to an increase in the metallic copper phase, while the Cu + constituent decreases (Figure 10) which in turn is more beneficial for copper recovery during slag cleaning.
