Method for recycling lead from waste glass containing lead |
| abstract |
Disclosed is a method for recycling lead from waste glass containing lead, which comprises the following steps: mechanical crushing waste glass containing lead, ball milling and screening to obtain glass powder containing lead; alkaline roasting the glass powder containing lead to obtain a roasted material; mixing polycarboxylic acid complexant and nitric acid to produce leaching agent, and then placing the roasted material into the leaching agent to obtain leachate; regulating pH value of the leachate to solidify metal ion to obtain precipitate, separating and removing impurities, rinsing and drying to obtain chemical product containing lead. The method avoids environment pollution caused by waste glass containing lead. |
