Аннотация

The bisulfate process is promising for the development of closed cycle technologies for the processing of alumina-containing raw materials with reagent recovery. Implementing this process requires a rational method for separation of ammonium bisulfate into the sulfate and sulfuric acid in each cycle. The possibility of such separation was shown for the first time by modification of the acid retardation technique based on the sieve effect in the nanoporous medium. The proposed method solves the problem of reagent recovery, which is relevant for some industrial processes, and has prospects for the development of new ore processing techniques.
