Hydrothermal Sulfidation of White Lead with Elemental Sulfur

Abstract:

Hydrothermal sulfidation of pure white lead with elemental sulfur has been studied in the present paper. The variables considered in the study were temperature, time, particle size and elemental sulfur fraction in the reacting mixture. Temperature and time were the most two important factors, with an increase in temperature and holding time the sulfidation extent of lead improved greatly and the constituent of products changed a lot. At temperatures above 140°C, PbS and PbSO4 were the only stable reaction products in the sulfidation of white lead. The experimental data indicated that under the hydrothermal conditions with a particle size of -58+48 μm and sulfur fraction in reacting mixture of 8% at 140 °C for 90 min, and 86% of lead sulfidation extent was achieved.
