Abstract
Chlorination of sulfide minerals and several prepared metal sulfides was studied. The resulting data were analyzed with respect to kinetics of the reactions and application to nonpolluting methods of winning metals from sulfide ores. Sulfides of iron, copper-iron, nickel, lead, zinc, silver, bismuth, arsenic, rhenium, molybdenum, and tungsten were investigated at temperatures up to 600 deg c. Copper-iron, lead, and zinc sulfides showed at least some product- controlled (parabolic) kinetics at the lower temperatures within the temperature ranges studied, but only nickel and silver sulfides had chlorination rates controlled by parabolic reaction kinetics in the commercially important temperature range of 450 deg to 600 deg c.
