An excessive amount of lime which may be due to flocculation so that the viscosity of the slurry is increased to increase the diffusion resistance of the solvent so that a corresponding increase in the content of impurities in the solution the surface of the gold particles forming the thin film of calcium peroxide sodium cyanide and gold and hinder the role of oxygen the effect of reducing leaching when there is an insufficient amount of lime sodium cyanide

Aug 01 2006 the second mechanism by which sulfide minerals can impact on the gold leaching process is as a result of their solubility the experiments shown in fig 3 were only run for a short period of time and hence the nonoxidative dissolution of the sulfide minerals was limited since most sulfide minerals are to some extent soluble in cyanide solution it has been suggested that the dissolved species may affect the gold leaching
