EFFECT OF SILVER, NICKEL AND COPPER CYANIDES ON GOLD ...

Thus, many metalcyanide species occur in cyanide leaching process, but many of them adsorb weakly on carbon without affecting the gold adsorption. Among these metals, Ag and Ni exert negative effect on gold adsorption and in the case of Cu this effect depends on pH and free cyanide concentrations (Poinern et al., 2011; Fleming et al., 2011; Yin et al., 2011; Petersen et al., 1993). Therefore ...
