Способ относится к области гидрометаллургии платиновых металлов и может быть использован для извлечения палладия и платины из соляно-кислых растворов, образующихся при растворении анодных шламов. Способ заключается в том, что в раствор, образующийся после осаждения и отделения осадка хлорплатината аммония, постепенно вводят хлористый аммоний и одновременно пропускают газообразный хлор при соотношении реагентов 1 : 0,8 oC 2,0 и температуре 25-40°С. Способ позволяет упростить процесс за счет исключения стадий введения аммиака и соляной кислоты, образования и отделения осадка гидроксидов меди и железа, снизить потери платины и палладия, соосажденные с гидроксидами, на 2-2,5%.The method relates to the field of hydrometallurgy of platinum metals and can be used to extract palladium and platinum from hydrochloric acid solutions formed when anodic sludge is dissolved. The method consists in the fact that ammonium chloride is gradually introduced into the solution formed after precipitation and separation of the precipitate of ammonium chloroplatinate and at the same time chlorine gas is passed through at a reagent ratio of 1: 0.8 ° C and temperature of 25-40 ° C. The method allows to simplify the process by eliminating the stages of introducing ammonia and hydrochloric acid, the formation and separation of the precipitate of copper and iron hydroxides, reduce the loss of platinum and palladium, co-precipitated with hydroxides, by 2-2.5%.
