Novel Concentration Process for Platinum Group Metals in

As shown in Figure 3(a), the sulfurization of Cu by sulfur at 850 K (577 °C) produces copper (I) sulfide (Cu 2 S) under low-oxygen partial pressure and copper (II) sulfate (CuSO 4) under high-oxygen partial pressure.During the flotation process, Cu 2 S floats in the flotation solution, whereas CuSO 4 dissolves in the solution. In the latter case, it is expected …
