The reductive leaching of Copper and Cobalt ores using SO2 gas as reducing reagent is a complex process. During reductive leaching of Copper and Cobalt ores, first iron plays an important role as a catalyst because the direct dissolution of Heterogenite with soluble sulfite compounds is limited by migration into the solid pores, and secondly, iron has a saturation concentration controlled by the precipitation of Copiapite. The presence of phosphoric acid coming from the dissolution of pseudo malachite precipitates Iron as Strengite. Furthermore, the presence of Cobalt and Manganese ions in the leach solution produces dithionate in the first stage and Caro’s acid in the second stage by absorbing surface oxygen of the ore. Additionally, the absorption of surface oxygen by sulfite compounds decreases the acid consumption. This study elucidates these complex interactions and proposes insights into optimizing the leaching process.
