[0002] After recycling, waste batteries can be melted and re-refined to produce refined lead, soft lead and various lead-based alloys. Recycled lead occupies an important position in the lead industry. It not only reduces the consumption of primary lead ore resources, protects mineral reserves, extends the mining period of lead ore, but also is beneficial to environmental protection. More importantly, compared with primary lead, recycled lead has a high recovery rate, lower energy consumption and cost.
