The decomposition of ammonium jarosite bearing indium in NaOH medium were studied. The effects of NaOH addition, liquid-solid ratio, decomposition temperature and time on the decomposition ratio of ammonium jarosite were investigated, respectively, and the behavior of impurity elements, such as Zn, In, Cu, Cd, Pb, As, Sb, Sn and Ag in jarosite residues was also discussed.

摘 要：提出NaOH分解含铟铁矾渣新工艺，考察NaOH用量、液固比、温度和时间对铁矾渣分解率的影响，并讨论铁矾渣中杂质金属，如Zn、In、Cu、Cd、Pb、As、Sb、Sn和Ag等在NaOH分解过程中的行为。

The results show that the decomposition rate of ammonium jarosite can reach 98.03% under the following optimum conditions, which are m m=0.381 41, temperature 60 ℃, liquid-solid ratio 21, reaction time 2 h. During the alkaline decomposition, the impurity elements, such as Zn, In, Cu, Cd, Pb, Sb, Sn and Ag are left in the residue, while As is leached into the pregnant solution as AsO43 with leaching rate of 83.36%.
