Аннотация: The scope for using KSCN solutions in the field of gold leaching from chemical preparation products of hard arsenopyrite concentrates is shown. More than 95% gold is recovered in weak acidic solutions (pH = 2-5) at KSCN concentration 0.4 mol/L. The thiocyanate complexes are recovered on carbon adsorbents (BAU, UC, LKAU-4) as well aПоказать полностьюs on ion exchangers (AV-17-IOP, AP-100). The gold recovery degree is 99.2-99.8%. The desorption of gold from ion exchangers can be done by thiocarbamide solutions in H2SO4 at room temperature, and from carbon adsorbents by basic thiocarbamide solutions at similar to150 degreesC.
