【 摘 要 】

This paper aims to consider the treatment of jarosite residue using a different reducing agents, aluminum, magnesium, and carbon. The jarosite residue is not standard-it contains higher amounts of Pb and Ag, as well as in, Ga and Ge. We show thermodynamical conditions of gas phase equilibrium for the given experiments and predominance diagrams that show potential for obtaining critical metals in the metallic phase. Using a mixture of aluminum and magnesium, as reducing agents, showed proper fuming of Zn and Pb at a temperature of 1200 °C. However, magnesium alone, and carbon in the mixture of reducing agents cause poor results for zinc fuming, which is explained by the modeling of the given compositions.
