| Abstract: | In recovering Ge and Ag from the calcine and fume dusts mixture of Huidong Lead-zinc Mine, the flow sheet of hot acid leaching-halotrichite method mainly consists of neutral leaching, low-acid leaching, high acid leaching and jarosite precipitation. In the ten circulation periods, the technology flow sheet was carried out smoothly. The loss of Ge in halotrichite residue is less than 5.0%, when iron is precipitated by using ferric potassium alum instead of common Na or ammonium alum and the conditions are controlled at temperature about 95 °C for more than 3 h, pH values below 1. 5. Ge and Ag are concentrated in the high acid leached residue, and their contents are 0.032% and 0.162%, respectively, and the total recovery and direct recovery of zinc are 98.94% and 96.15%, respectively.
