Froth flotation. In principle, the copper slag flotation is quite similar to the flotation of Cu-bearing sulphide minerals ([68];[128]; [10, 22, 78]). The copper values present in the slag, either as independent metallic particles or in the form of sulphides, can be floated effectively.

Copper smelter slag and copper smelter slag flotation tailings were leached using sulphuric acid solutions, without or with the addition of either ferric sulphate or hydrogen peroxide.
A smelting plant in Bor extract copper from copper ores and copper concentrates by a pyro metallurgical process. During years of operation, a considerable amount of copper slag has been generated as a by-product and has been dumped. Copper contents in these slags are as high as 0.6 up to 0.8%.
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 ).
In order to minimise this loss, the slag is further treated to recover the valuable metal. One treatment method is via froth flotation in a Slag Flotation Plant. With its smelter operational for many decades, one customer recently replaced its slag flotation plant to further optimise metals recovery.

The copper slag produced by the slag cleaning furnaces as a final by-product, yields copper in the range of 0.55–1.3 wt.% in the discarded slag, with copper losses of most plants in the discarded slag limited between 0.8 wt.% and 1.0 wt.% (Coursol et al., 2012). However, the final copper slag still contains large amounts of valuable …
