Metal biorecovery in acid solutions from a copper smelter slag

Carranza et al. (2009a) compared copper yields obtained from various size fractions of a Cu-rich converter slag sample using ferric sulfate and concluded that mild grinding (D 80 = 83.5 μm) was sufficient to improve the leaching of Cu and Zn. In the current work the slag was ground to size 73% 45 μm before the slag concentrator and hence further grinding may not be warranted. Increasing
