摘要： A method for recovering lead from lead-containing discarded electronic waste cathode ray tube glass includes the steps of taking a sample of cathode ray tube lead-containing funnel glass, crushing to obtain CRT glass powder, then uniformly mixing zero-valent iron powder with the CRT glass powder according to the mass ratio of 0.1-1.5:1, performing heat preservation at a temperature of 610-960° C. for 3-180 min, and further cooling to extract the metallic lead from a SiO2 reticular glass structure of the CRT glass. This can be applied to pretreatment of the lead-containing waste CRT glass, and the metallic lead is extracted from the reticular silicate structure of the lead-containing waste CRT glass by adding the zero-valent iron in the thermal treatment process so that disposal rate of electronic wastes is improved and ecological safety is ensured. This method has important environmental, social and economic significance and broad application prospects.
摘要翻译：从含铅废弃电子废阴极射线管玻璃中回收铅的方法包括以下步骤：取阴极射线管含铅漏斗玻璃样品，粉碎得到CRT玻璃粉末，然后将零价铁粉与 CRT玻璃粉末按质量比为0.1-1.5:1，在610-960℃的温度下进行3-180分钟的保温，并进一步冷却，从二氧化硅网状玻璃结构中提取金属铅 CRT玻璃。这可以用于含铅废物CRT玻璃的预处理，并且通过在热处理工序中添加零价铁，从含铅废液CRT玻璃的网状硅酸盐结构中提取金属铅，使处理率的电子废物得到改善，确保了生态安全。这种方法具有重要的环境，社会和经济意义，应用前景广阔。
