Abstract
В способе растворенный целевой металл смешивают с раствором, содержащим по меньшей мере один вспомогательный металл, для осаждения растворенного целевого металла в виде порошка (14) целевого металла. В способе первую часть содержащего кислоту исходного раствора подают в анодное пространство (6) электролитической ячейки в качестве анодного раствора (1) для приведения в контакт с анодом и расходным материалом, содержащим целевой металл, а вторую часть содержащего кислоту исходного раствора, который также содержит вспомогательный металл, подают в катодное пространство (8) электролитической ячейки в качестве катодного раствора (3) для приведения в контакт с катодом (4); целевой металл окисляют и растворяют в анодном растворе (1) путем пропускания электрического тока через анод (2); целевой металл, содержащийся во второй части исходного раствора, восстанавливают в катодном пространстве (8), а анодный раствор и катодный раствор подают в камеру (12) осаждения для смешивания растворенного, окисленного целевого металла и второй части исходного раствора, содержащего восстановленный вспомогательный металл.In the method, the dissolved target metal is mixed with a solution containing at least one auxiliary metal to precipitate the dissolved target metal as a powder (14) of the target metal. In the method, the first part of the acid-containing feed solution is fed into the anode space (6) of the electrolytic cell as an anode solution (1) for contact with the anode and the consumable material containing the target metal, and the second part of the acid-containing feed solution, which also contains the auxiliary metal is fed into the cathode space (8) of the electrolytic cell as a cathode solution (3) to be brought into contact with the cathode (4); the target metal is oxidized and dissolved in the anode solution (1) by passing an electric current through the anode (2); the target metal contained in the second part of the initial solution is reduced in the cathode space (8), and the anode solution and the cathode solution are supplied to the deposition chamber (12) for mixing the dissolved, oxidized target metal and the second part of the initial solution containing the reduced auxiliary metal.
