Claims (1)

Способ осаждения ионов марганца из растворов солей кобальта в присутствии окислителей, отличающийся тем, что на первой стадии осуществляют осаждение ионов марганца и кобальта щелочным реагентом при рН≥6, а в качестве окислителя используют перекись водорода, на втором этапе отфильтрованный осадок обрабатывают кислым раствором при рН≤4 для растворения соли кобальта, при этом введенная на первом этапе перекись используется на восстановление ионов кобальта, в осадке концентрируются соединения марганца.The method of deposition of manganese ions from solutions of cobalt salts in the presence of oxidizing agents, characterized in that the first stage is the deposition of manganese and cobalt ions with an alkaline reagent at pH≥6, and hydrogen peroxide is used as an oxidizing agent, at the second stage, the filtered precipitate is treated with an acid solution at pH ≤4 for dissolving cobalt salt, while the peroxide introduced in the first stage is used to reduce cobalt ions, manganese compounds are concentrated in the precipitate.
