Аннотация: Gold recovery from arsenopyrite coaly hard concentrates obtained by ore flotation concentration has been studied. The thiosulphate leaching of the products obtained after the chemical preparation of the concentrates was carried out in the system Na2S2O3-NH3-H2O at 20-22 degreesC. The gold recovery on ion exchangers and carbon adsorbents from the thiosulphate solutions was investigated. It was found that the use of strong basic or polyfunctional anion exchangers of macroporous or porous structure is the most applicable for hydrometallurgical technology.
