Recovery of copper from reverberatory furnace slag
2004-3-1 The optimum condition for flotation of the reverberatory furnace slag at Sarcheshmeh Copper Complex is as follows : pH=11.5; R407=30 g/t; solid in pulp=30%; flotation time=12.5 min; MIBC=35 g/t. Slow cooling of the molten slag (in the range of 1300–900 °C) increases the copper recovery considerably (about 85%), and can also reduce the comminution time to less than 30 min.
