THE IMPORTANCE OF OXIDATIVE ROASTING FOR THE OXIDATION OF RESISTANT CARBONCONTAINING SULFIDE ORES
The article discusses the application of oxidative roasting for processing refractory carbonaceous sulfide ores. The impact of carbon on metal recovery reduction and its oxidation mechanisms are analyzed. The key technological parameters of the process, its effect on the efficiency of subsequent hydrometallurgical metal extraction, and measures to minimize environmental impact are presented.
