Özet:

 

A novel technique for silver extraction from Ag2S is described.  The  method utilizes thiosulphate as complexing reagent and the redox  reaction between SO2 added as Na2SO3 powder and H2S gas evolved.  The parameters of the reaction such as pH, the reaction temperature,  the complex equilibrium of Ag+ ion with thiosulphate and the  solubility of Ag2S were investigated.  Silver ions, obtained by this  means are collected in high purity (99%) by applying appropriate  electrolysis conditions.  The interference from other metallic  impurities, namely copper, gold, iron and zinc, is eliminated by  choosing an appropriate electrolysis potential.
