Claims (1)

Способ переработки содопоташного раствора, включающий политермическую упарку содопоташного раствора с выделением из него последовательно продукционной соды, оборотной двойной содопоташной соли, продукционного поташа и возврат поташного маточного раствора в технологический цикл глиноземного производства, отличающийся тем, что в поташном маточном растворе перед возвратом его в технологический цикл глиноземного производства снижают молярный индекс калийной щелочи до 55±5% путем гидрохимической конверсии им сульфатной соли натрия или ее смеси с содой с выделением в осадок сульфата калия.A method for processing soda-potash solution, including polythermal evaporation of soda-potash solution with the release of sequentially production soda, reverse double soda-potash salt, production potash and return of potash mother liquor to the alumina production cycle, characterized in that in the potash mother liquor before returning it to the production cycle alumina production reduces the molar index of potassium alkali to 55 ± 5% by hydrochemical conversion of sodium sulfate salt or mixtures thereof with soda with precipitation of potassium sulfate.
