Breton Canadian primary smelter refining crude lead after the initial fire, calcium, magnesium dross bismuth addition, the output of the bismuth-containing 2% to 4%, by basic enrichment, the output of the Pb-Bi co Gold contains 8% to 10%, directly enriched with chlorine gas, enriched to Pb-Bi alloy containing more than 65% bismuth, added zinc and silver , chlorinated dezincification, lead, and then alkaline refining, The output is fine. The process flow is shown in Figure 1. Figure 1 Flow chart of the recycling process at the Burlington plant The process is characterized by two times of chlorination and lead removal. The first chlorination acts to enrich bismuth (Bi>65%); the second chlorination removes the effect of residual lead.
