Abstract

Изобретение относится к способу выщелачивания материала, содержащего ценный металл, и осаждения ценного металла в виде тонкодисперсного порошка путём изменения электрохимического потенциала металла-посредника в растворе. На стадии выщелачивания металл-посредник или вещество-посредник в растворе электролита находится в высокой степени окисления, а на стадии осаждения в раствор подают другой раствор электролита, в котором металл-посредник или вещество-посредник находится в низкой степени окисления. После стадии осаждения раствор, содержащий посредник, подвергают электролитической регенерации, в ходе которой часть посредника вновь окисляют в анодном пространстве до высокого значения потенциала, а часть - восстанавливают в катодном пространстве до низкого значения потенциала.
