RECOVERY OF COPPER FROM SMELTING SLAG BY

2015-11-11 · simplified process flowsheet for the recovery of copper from the reveberatory furnace slag using sulphation roasting (i.e., acid baking) and water leaching is shown in Figure 4. Assuming that the calcine was produced at 350 oC and subsequently water leached at 20% solids (i.e., at a solid-to-liquid ratio of 1:5), then it can also be assumed that copper and iron extractions of 77% and 46%, respectively, could be achieved (see Table 6). Based on this data, it can be calculated that the concentrations of copper and iron in the pregnant leach solution would be about 1 g/dm3 and 24 g/dm3, respectively. This concentration of copper would be high enough for solvent extraction with oxime based reagents such as LIX® 84-I or LIX® 984N, but iron would have to be reduced to levels below about 2 g/dm3 prior to the copper
