Abstract
The Bureau of Mines, under a cost-sharing, cooperative research program with lead producers, is studying a process to eliminate sulfur oxide generation and to minimize lead emissions in the production of lead metal. The new process consists of leaching lead sulfide concentrate with a ferric chloride-brine solution to produce lead chloride, which is then converted to lead metal by fused-salt electrolysis. For 18 months the Bureau operated an integrated process investigation unit, includng both leaching and electrolysis sections, which was designed to treat 750 lb of concentrate and to produce 500 lb of lead metal per day. Electrowinning of lead metal is accomplished in a 3,000-amp fused-salt cell at 450 deg c, utilizing a licl-kcl-pbcl2 electrolyte. This paper describes the development, construction, and operation of this 3,000-amp cell.
