Several plants recover the copper contained in the copper slag by flotation. This method is generally appropriate for liberated metallic copper and sulfide minerals. It is unsuitable for recovering base metals such as cobalt, zinc, and nickel and forms of oxides or doped slags (Aatach et al., 2020).

Currently, the slags are sent to a milling and flotation plant for liberation and recovery of residual copper. The copper recoveries realized in the plant are much lower than expected and it has been postulated that some copper minerals may be occurring in forms that are more difficult to float like oxides or fine disseminations in the gangue ...

In this paper, the results of the study of application of thionocarbamates in copper slag flotation are presented. Chemical analysis of smelter slag sample obtained from Flotation plant in Bor, Serbia, showed that it contains 3.56% of copper, of which over 73% is in the sulphide form, as well as 0.58 g/t of gold and 11.30 g/t of silver.
