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. Copper extraction from the slag was typically found to be twice as high as that from the slag flotation tailings. Hydrogen peroxide was determined to be the best lixiviant. Thus, copper and iron extractions were ...

Relative significance of flotation parameters (based on difference between max and min. values) indicates that pH has the most significant effect on the recovery of nickel, copper and cobalt during ...
flotation tailings was as low as 33% (Urosevic et al., 2015). Accordingly, the objective of the present work was to investigate whether the introduction of a pyrometallurgical pre-treatment step to break down the slag structure, thereby rendering copper-containing phases amenable to leaching, would result in an increase in copper recovery.
froth flotation for sulfide copper ore located at depth heap leaching, for oxidized copper ore located near the surface. In this case, an important characteristic appears the need to consider the soluble copper grade as an auxiliary variable, since it is only part of what the acid has been able to dissolve that is finally recovered.
