Roasting of sulfide minerals is a crucial process in the extraction of metals, where air, often enriched with oxygen, interacts with sulfide mineral concentrates at elevated temperatures. This study aims to explore the various objectives of roasting, the chemical and thermodynamic intricacies involved, and the techniques employed to enhance metal recovery. Methodologically, the research utilizes a comprehensive review of current literature, outlining the reactions that occur during roasting, the conditions leading to optimal extraction, and the use of fluidized beds for efficient processing of fine concentrates. Notably, the findings reveal that the product composition is heavily influenced by multiple factors including temperature, gas partial pressures, and particle size. The predominant objective is to produce metal oxides and controlled amounts of soluble salts while minimizing impurities in leach liquors. The results indicate that roasting temperatures significantly affect the formation of desired products, emphasizing the necessity for precise temperature control during the roasting process to achieve a favorable mineralogical composition. These insights can guide industry practices, ensuring better efficiency in metal recovery from sulfide ores.
