Abstract
Now manufacturing of rare chalcogens and precious metals is realizing in processing of sulphidic polymetallic raw material, mainly from muds of copper and nickel electrolysis. In the article the possibility of selenium extraction from alkaline solutions, using electrolysis. Detachment of choosing pH of initial solution are made. Also you can find results of polarizing admeasurements of selenium extraction from selenite – biselenite solutions. The conclusions of possibility of selenium procurement, using electrolysis.
