The influence of mechanical activation of chalcopyrite on the selective leaching of copper by sulphuric acid [PDF]

Metalurgija, 2006
In this paper chalcopyrite, CuFeS2, has been selective leached by H2SO4 as leaching agent (170 g/dm3) in procedure of hydrometallurgical production of copper. Mechanical activation of the chalcopyrite resulted in mechanochemical surface oxidation as well

Hydrometallurgical recovery of tin and lead from waste printed circuit boards (WPCBs): limitations and opportunities

Metalurgija, 2016
In this paper, possibility for selective Pb and Sn recovery, using three different solutions of NaOH, HCl and HNO3, from WPCBs containing low concentrations of Pb and Sn is presented.

Influence of Mechanical Activation on the selectivity of Bornite Leaching

Acta Montanistica Slovaca, 2004
Sulfidic mineral bornit Cu5FeS4 was exposed to the selective leaching of copper in H2SO4 solution. Surface changes of the mechanically activated sulphide were investigated before and after leaching using the infrared spectroscopy and the scanning electron microscopy.
