Abstract:
There is extensive literature on the investigations carried out to determine the process operating conditions for extraction of nonferrous, base and precious metals from complex sulphide resources. Successful aqueous processing of those ores depends on the composition and mineralogy of raw materials and on their leaching behaviour. Systematic studies have been made to understand the oxidation behaviour and dissolution reaction mechanisms operative while pure copper, zinc and lead sulphide minerals and mixtures are treated by oxidative ammonia leaching. The kinetic expressions obtained for the dissolution of bulk concentrates are discussed as a case study. This paper also describes how one approaches the problem of designing the experiments for economic extraction of metal values from multimineral sulphides.
