6 FAQs about [Methods for dismantling lead-acid batteries in smelters]
How pyrometallurgy is used in recycling lead-acid batteries?
The method has been successfully used in industry production. Recycling lead from waste lead-acid batteries has substantial significance in environmental protection and economic growth. Bearing the merits of easy operation and large capacity, pyrometallurgy methods are mostly used for the regeneration of waste lead-acid battery (LABs).
How are lead-acid batteries recycled?
Most small lead-recycling enterprises adopt the mixed smelting of spent LABs on the alloy grid plate and waste lead paste reverberatory furnaces before preprocessing, resulting in the underutilization of alloy components . America, which has a slightly lower lead–acid battery output than China, has only six recycling enterprises.
What is hydrometallurgical lead recycling?
In hydrometallurgical lead recycling, the reduction of the salts in lead paste occurs though a solution-based methodology.
Why do secondary smelters buy pre-sorted battery fractions?
Some secondary smelters also buy up pre-sorted battery fractions, e.g. grids and lead paste without casings and separators, in addition to complete batteries. The lead smelters thus save several processing stages and do not have to deal with casing and separator wastes. They are therefore willing to pay a higher price for the material supplied.
What are the contents of a lead-acid battery?
The contents of a lead-acid battery are the sulfuric acid and lead sulfate battery paste, the metallic and oxidic lead grid parts, the plastic battery casings, and the silica separators. Although the methods have changed over the years and vary from plant to plant, the batteries must initially be broken and separated.
Can China smelt recycled lead?
In recent years, China has made major breakthroughs in the direct smelting of lead-containing waste and in co-smelting technology with primary lead ore, but the production capacity of recycled lead is scattered.
