摘要：

Hydrothermal sulfidation of pure cerussite with elemental sulfur has been reported in the present paper. The variables considered in the study were temperature, time, particle size and elemental sulfur fraction in the reacting mixture. Temperature was the most important factor, at temperatures above 180 degrees C PbS and PbSO4 were the only stable reaction products in the sulfidation of cerussite. The experimental data indicated that under the hydrothermal conditions with a particle size of -74+58 m and sulfur fraction in reacting mixture of 15% at 200 degrees C for 120 min, and 92% of lead sulfidation rate was achieved.
