Description
Бораты часто содержат до 25% окиси магни .Borates often contain up to 25% magnesium oxide.
При разложении таких боратов серной кислотой в раствор переходит борна кислота и MgO в виде MgSO4.When such borates are decomposed with sulfuric acid, boric acid and MgO pass into the solution as MgSO4.
После кристаллизации борной кислоты из раствора маточник обычно примен етс дл обработки свежей руды. При содержании в породе окиси мвгни раствор быстро становитс насыщенным в отношении MgSO.), что делает невозможным дальнейшее пользование маточником в качестве оборотной жидкости в замкнутом процессе, так как одновременно с борной кислотой начинает выдел тьс и MgSO4 aq.After crystallization of boric acid from solution, the mother liquor is usually used to process fresh ore. When the oxide content in the rock is mvgni, the solution quickly becomes saturated with respect to MgSO4.), Which makes it impossible to continue using the mother liquor as a circulating fluid in a closed process, because simultaneously with boric acid MgSO4 aq begins to be released.
Насто щее изобретение позвол ет получить из маточника чистую борную кис.Юту и MgSO - aq, который также вл етс ценным продуктом, при одновременном непрерывном оборачивании маточника в производстве без каких-либо дополнительных затрат реагентов и оборудовани .The present invention makes it possible to obtain pure boric acid from the mother liquor. Uta and MgSO - aq, which is also a valuable product, while simultaneously wrapping the mother liquor in production without any additional costs of reagents and equipment.
Предлагае.мый метод основан на том, что при введении в маточник серной кислоты достаточной концентрации (после выделени из него борной кислоты) сульфат магни выпадает в осадок.The proposed method is based on the fact that when sulfuric acid of sufficient concentration is introduced into the mother liquor (after separation of boric acid from it) magnesium sulfate precipitates.
После отделени сульфата обедненный .магние.м маточник, содержащий серную кислоту, возвращаетс , после предварительного прибавлени к нему промывных вод (что снижает в свою очередь концентрацию Alg), на разложение новой порции породы. Таким образом получаетс в качестве дополнительного продукта с льфат магни , а возвраш.аемый маточник содержит такие количества его, которые не вызывают загр знени борной кпслоты во врем ее кристаллизации.After sulphate is separated, the depleted .magnesium m liquor containing sulfuric acid returns, after the preliminary addition of wash water to it (which in turn reduces the Alg concentration), to the decomposition of a new portion of the rock. Thus, it is obtained as an additional product with magnesium sulfate, and the mother liquor returned contains such quantities of it that do not cause contamination of the boron cell during its crystallization.
Серна же кислота, идуща на разложение породы, вводитс в цикл не в реакционный аппарат, где находитс порода, а раньше, именно в точке обработки .маточника.Sulfuric acid, going to decompose the rock, is not introduced into the cycle into the reaction apparatus where the rock is located, but earlier, precisely at the processing point of the master.
Маточник оборачиваетс непрерывно , и потер борного ангидрида с ним исключаетс , поскольку благодар подъему температуры ;50-60°) борна кислота не кристаллизуетс при введении серной кислоты.The mother liquor is wrapped continuously, and loss of boric anhydride is eliminated with it, because due to the rise in temperature (50-60 °), boric acid does not crystallize when sulfuric acid is injected.
Описанный спссоб иллюстрируетс прилагаемой схемой.The described procedure is illustrated by the attached scheme.
