Abstract
This report presents results of investigations on the kinetics of leaching zinc-lead concentrates with chlorine. The objective was to determine the kinetic order and mechanisms involved in the reactions between sphalerite (zinc sulfide) and galena (lead sulfide) with chlorine. The influence of copper on the extraction rates also was studied. The rates of reaction for both species were zero order at 100 deg. C, the rate limiting step being the chemical reaction. The addition of cupric chloride increased the extraction of both zinc and lead.
