Mechanical Activation of Antimony Sulfide Concentrates Combined with Pyrometallurgical Chlorination

Abstract

Research on a combined method of chlorination roasting of a mechanically activated antimony sulfide concentrate from the Anzob Mining and Processing Plant in the Republic of Tajikistan with sodium chloride was carried out. The influence of the main factors - temperature, processing time, charge composition – has been determined which allowed an almost twofold increase in the degree of antimony extraction and at lower process temperatures
