Description
Известно разложение природных боратов .шгни серной кислотой при нормальном давлении и температуре 95°. При этом соотношение борной кислоты и окиси магни в полученном растворе сохран етс тем же, что и в исходной руде, т. е. сульфа г магни совместно с борной кислотой полностью нереходит в раствор. При кристаллизации борной кислоты из такого раствора до 25% ее остаетс в маточнике.Known decomposition of natural borates. Shnny sulfuric acid at normal pressure and a temperature of 95 °. At the same time, the ratio of boric acid and magnesium oxide in the resulting solution is kept the same as in the original ore, i.e., sulfide and magnesium together with boric acid does not completely dissolve into solution. During the crystallization of boric acid from this solution, up to 25% of it remains in the mother liquor.

Известно, что растворимость сульфата магни с повышением температуры резко снижаетс . Поэтому ука; ,;и1нь й прием приводит к значительному умеиьшению количества переход ш ,его в раствор магни иозво . ет отде.тить последиий в виде сер (окпс.юй соли в.месте со шламом нег .осредственно в процессе раз.юже11ИЯ боратов. Благодар этому уменьшаетс обидий объем циркулирующих растворов в производственном цикле и выход борноГт кислоты увеличиваетс до 90%.It is known that the solubility of magnesium sulfate decreases sharply with increasing temperature. Therefore uka; ,; and the intake leads to a significant decrease in the amount of transition, it goes into a magnesium solution. It can be used to determine the sequence in the form of sulfur (okp.suy salt in place with the sludge neg. directly in the process of dilution of borates. Due to this, the amount of circulating solutions in the production cycle is reduced and the yield of boric acid increases to 90%.
