Abstract
The Bureau of Mines, under a cooperative research agreement with lead producers, is conducting a feasibility study of a process to minimize pollution caused by sulfur oxide and lead. The process involves ferric chloride leaching of galena to produce lead chloride and fused-salt electrolysis of the lead chloride to produce lead and chlorine. The chlorine produced by electrolysis is used directly to regenerate ferric chloride in the leach solution. The study is being conducted in a process development unit designed to produce about 500 pounds per day of lead metal, operating on an integrated basis. This report describes the equipment and operating procedures, and presents a preliminary evaluation of the results with respect to process performance, equipment corrosion, impurity buildup, and air monitoring.
