【 摘 要 】

In view of the annual increase in ore processing output forlow grade or refractory gold-bearing ores, as well as recoverable rawmaterials, stricter requirements for completeness of gold extraction andenvironmental safety, the interest is rising in possible alternatives tosubstitute the cyanide process used in gold mining practice. One of suchalternatives is to convert metals into solutions of various chemicalcompositions by means of electric current-electrochemical leaching-followed bymetal sorption extraction. This paper deals with the issues of sorptionbehavior of noble (gold, silver) and non-ferrous (copper, iron, cobalt, zinc,nickel, manganese, lead) metals from thiosulfate solutions for chemical andelectrochemical leaching of concentrates of two mineral deposits using variousanionites. Factors affecting metal uptake most significantly were determined.Degree of zinc and nickel sorption extraction from electrochemical leachingsolutions made 99%. It has been established that the nature of metal sorptionextraction from process solutions is connected with the micro structure ofleaching solutions having quasi-homogeneous structure.
