Изобретение относится к электролитическому способу экстракции платины высокой чистоты из концентрированных солянокислых растворов загрязненной платины. В способе согласно изобретению процесс очистки проводят к электролитической ячейке, разделенной катионообменной мембраной в потенциостатических условиях или при контролируемом напряжении 2,5 - 8 В при плотности тока 0,3 - 12,5 А/дм2 и извлекают осажденные металлы платинового сплава. Концентрированные растворы металлической платины имеют содержание загрязненной платины 50 - 700 г/л и суммарное количество примесей ≤5000 ппм. Способ согласно изобретению осуществляют с минимальными требованиями к безопасности технологии и оборудования, он оказывает минимальную нагрузку на окружающую среду и намного эффективнее по трудозатратам и стоимости.The invention relates to an electrolytic method for the extraction of high purity platinum from concentrated hydrochloric acid solutions of contaminated platinum. In the method according to the invention, the cleaning process is carried out to an electrolytic cell separated by a cation exchange membrane under potentiostatic conditions or at a controlled voltage of 2.5-8 V at a current density of 0.3-12.5 A / dm 2 and the deposited platinum alloy metals are recovered. Concentrated solutions of metal platinum have a contaminated platinum content of 50 - 700 g / l and a total amount of impurities of ≤5000 ppm. The method according to the invention is carried out with minimal safety requirements for technology and equipment, it has a minimal environmental load and is much more efficient in terms of labor and cost.
