【摘要】 研究了加压氰化法从失效汽车催化剂中选择性浸出铂族金属 ,考察了加压氰化过程影响金属浸出率的各种因素。实验结果表明 :对 2 0 0 g处理批量的小实验铂族金属氰化浸出率分别达到Pt98% ,Pd99% ,Rh96 % ;千克级放大实验可完全重现小实验结果 ,且该工艺也适应于其他类型失效催化剂的处理。更多还原

【Abstract】 Pressure cyanide selectively leaching of platinum-group metals(PGMs) from spent automobile catalysts was studied, and various effects on the extraction of cyanide leaching were also discussed. The results show that the extraction ratio of platinum, palladium and rhodium for 200 g batch process can reach 98%, 99% and 96% respectively, and also better for 1 kg batch process. The method can also adapt to the treatment of other kinds of spent auto-catalysts.更多还原
