Purpose of the development: No-waste and ecologically acceptable technology for processing of battery scrap and other kinds of secondary raw materials. The technology ensures obtaining of commercial product: lead of CO and CO1 brands, antimonious or bismuthous lead, copper matte, arsenous ligature, slag, gypsum and other sulfur-containing products, polypropylene and polyvinylchloride.

Recommended application field: Different areas of national economy.

Advantages over analogues: As compared with blast-furnace smelting and smelting in short-barrel rotary kilns the technology ensures (with equal gas purification) more than a fivefold reduction in lead-containing dusts and sulphurous anhydride emissions into the atmosphere per unit of smelted lead, including in case of enrichment of blast with oxygen; Simplicity of smelt temperature control via variation of voltage at electrodes and depth of their submersion into the slag; Minimum amount of off-gases; Possibility of operation on slags in a wide range of compositions by slag-forming components; Reduction of slag output from 20-25 % up to 3-5 % and of coke consumption from 10-12 of % up to 3-4 %. The technology has no analogs. A significant amount of know-how is used at the lead bullion refining stage.

The development stage readiness: Introduced in production

Description of the development:
()
The processing technology includes: mechanized preparation of battery scrap, smelting, refining of lead bullion and processing of the recycled wastes to obtain commercial products. Smelting itself is performed in an electro-thermal furnace employing technology distinguished from the conventional methods by excluding use of soda as a fluxing agent. No matte is formed during the process. Slag formation depending on the ash content in the coke and scrap separation quality only is minimized. Processing of lead secondary raw materials smelting products (slag, drosses, skimmings) and ebonite fraction is performed in a fuming furnace of a unique proprietory design. The process has been patented in the Russian Federation.
