Abstract:In recent years,the recovery of rare metal condary resources has developed rapidly.The development trend of the condary resource recovery of precious metals was analyzed.The advantages of the condary resource treatment of precious metals in large-scale lead-copper smelter,side-blown melting tank and airtight oxygen-enriched negative pressure melting were introdu
ced.The industrial application of the precious metals catalyst in the treatment of failure is introduced.The advantages of side blowing smelting in treating lead anode slime were compared.The production practice of pre-removal of arnic and as solidification of lead anode slime was briefly described.The typical new technology of waste paration of electro contact alloy was analyzed.Evaluated the low concentration SO2waste free treatment technology introduced in condary resource smelting of rare metal and introduces the hydro-cyclically electrolytic puri行cation of silver waste liquid.Advocate the u of new technology,promote the transformation and upgrading of rare metal condary resource recovery process.
Key words:precious metals;condary resource;cleaner production;recovery technology
废弃物的回收利用，变废为宝、循环利用是朝阳产业。垃圾是放错位置的资源，把垃圾资源化，化腐朽为神奇，是一门艺术。困扰国人多年的垃圾分类也终于进入实施阶段，电子废弃物集中分类为处置提供了更好的原料品质，“城市矿产”收集更加规范有序。稀贵金属二次资源回收是公众支持、政府鼓励的朝阳行业，各项配套政策正在逐步落实。
稀贵金属由于具有优良的化学稳定性、催化活性及独特性能，在汽车工业、化学工业、石油化学工业、饰品、金融储备、航空航天等领域应用广泛，因此每年将产生大量的失效催化剂和其它废弃物料，其中富含稀贵金属。稀贵金属二次资源的特点
