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.

Abstract: A method of recovering the metal from automobile scrap and electronic waste. It includes separating the automobile scrap and the electronic waste to provide some metal pieces, washing and/or shredding and/or selecting said metal pieces to provide some groups of metal pieces having the same metal element, making a full-elemental analysis, comparing the weight of different metal pieces having the same metal element and attaining different combinations of value, weighted averaging the combination of value to calculate the full-elemental weighted average according to the different combinations of value, comparing the different full-elemental weighted averaging to different composite material, and finding a optimal set or some optimal sets, further disposing metal pieces according to the optimal set, and manufacturing alloy. Present invention has a lot of advantages, such as reducing pollution and cost, and processing more waste.
