Influence of Mechanical Activation on the selectivity of Bornite Leaching

open access: yesActa 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.

NH4Cl selective leaching of basic oxygen furnace slag: Optimization study using response surface methodology

open access: yes, 2016
The basic oxygen furnace slag (SL) was selectively leached by NH4Cl. Response surface methodology and the central composite design (CCD) were employed in determining the optimal condition.
