Coprocessing and resource utilization method of invalid platinum group metal-containing catalyst and magnesium slag
The invention relates to the field of recycling and comprehensive utilization of nonferrous metal resources. The invention particularly relates to a cooperative treatment and resource utilization method for an invalid platinum group metal-containing catalyst and magnesium slag. The invention discloses a cooperative treatment and resource utilization method of an invalid platinum group metal-containing catalyst and magnesium slag. The method comprises the following steps: A, pretreatment: the particle size of a refined material is 60-200 meshes; b, pellet prefabrication, wherein the prefabricated pellets are in an ellipsoidal shape; c, drying, wherein the drying temperature is 120-300 DEG C, and the drying time is longer than 3 h; d, melting and enriching to obtain molten liquid; and E, performing supergravity slag-gold separation to obtain the platinum-containing palladium-rhodium alloy. According to the method, the failed pellets containing the platinum group metal catalyst, the magnesium slag, a small amount of cosolvent and the like are prefabricated and melted, platinum group metal Pt, Pd and Rh are enriched, a metal trapping agent and a slag former are not additionally added, the production cost is effectively reduced, meanwhile, reutilization of the magnesium slag is achieved, the method is environmentally friendly and green, and the comprehensive utilization rate of solid waste resources is increased.
本发明涉及有色金属资源循环综合利用领域。具体涉及一种失效含铂族金属催化剂与镁渣的协同处理资源化利用方法。一种失效含铂族金属催化剂与镁渣的协同处理资源化利用方法，按如下步骤依次进行：A、预处理：细化后物料粒径为60‑200目；B、球团预制：预制球团为椭球状；C、烘干：烘干温度为120℃‑300℃，烘干时间大于3h；D、熔融富集：得到熔融液；E、超重力渣金分离：得到含铂钯铑合金。本发明将失效含铂族金属催化剂、镁渣和少量助溶剂等球团预制熔融，富集其中铂族金属Pt、Pd、Rh，该方法不再另外添加金属捕集剂和造渣剂，有效降低生产成本，同时实现了镁渣的再利用，环保绿色，提高了固废资源综合利用率。
