A variety of modeling techniques can be utilized to forecast metal production at heap leaching operations. These approaches reflect a wide range of complexity, flexibility, time to implement, cost, and accuracy. For many operators, a spreadsheet-based modeling technique is attractive since the calculations are directly accessible, models can often be developed by site staff, and the results are generally...
Subtractively normalised Fourier transform infrared spectroscopy (SNIFTIRS) studies are reported on the electrical polarisation of nickel (Ni), copper (Cu) and gold (Au) electrodes in KCN dissolved in the polar aprotic solvent, dimethyl sulfoxide (DMSO) with tetrabutyl ammonium perchlorate (TBAP) (0.1 mol L−1) as supporting electrolyte. These studies have shown clearly that each of the metal electrodes...
