Marble powder recycling battery lead

Release date:2017-06-08 Author:亿欣公司 Click:

  Over the years, some professional factories have used soda ash as a cosolvent to recover battery lead. An Italian company has now replaced the soda ash with marble powder from sawn marble waste. The advantages of this are: reducing production costs and bringing waste into new production processes. Calcium carbonate is mixed with other additive components (silica sand, iron filings, carbon, lead compounds of batteries, sulfates and oxides) to recover battery lead and produce a waste containing calcium oxide and silicate. , iron oxide and metallic iron, and 2-3% lead.

  In the past, the use of soda ash recovery time to send toxic waste to the discharge site was not available. Now, due to the incorporation of marble waste slurry, the lime contained in it does not hinder the coagulation of waste with cement and sand, so it can be fully utilized. For example, it should be used as a stable compact for washing machine washing drums, because this waste contains 50% iron, which is significant. A factory in Italy recycles 800 tons of battery lead per month, consumes 150 tons of marble powder, and produces 2,000 tons of this waste every day.
