An integrated technology has been developed for processing of lead-containing man-caused middlings and waste. The technology allows extracting lead and valuable metals as alloys from man-caused and secondary raw materials. The processed materials may be waste storage batteries or dusts, cakes and mattes, which contain lead, copper, zinc, cadmium, arsenic, antimony and noble metals, from copper smelters, zinc and leadproducing enterprises. Quality of the product is in compliance with the national GOST standards.
• A prototype electrolyzer, which has no analogs in the world, has been developed.
• Large-scale laboratory tests on electrical refinement of black lead, which was made from waste storage batteries, have been performed under the current load of 1000 A.

      ADVANTAGES
• The technology allows refinement of black lead in a single apparatus.
• The final products are commercial lead, leadantimony and lead-bismuth alloys.
• The process is managed so that formation of gaseous and dust effluents is avoided.
• A patent has been issued.
