Description

При разложении борномагниевых ми- I нералов (например, индерских месторожденкй ) серной кислотой ноЛучаетс  в качестве отброса расТв;Ор сернокислого магни .In the decomposition of boron-magnesium minerals (for example, in the Indian deposits) with sulfuric acid, it is obtained as a waste of rasTv; Or magnesium sulfate.

Согласно насто щему изоб:ретен«ю, i предлагаетс , в цел х использовани  св занной серной кислоты маточных щелоков, измельченную породу нодвергать электролизу с нерастворимым , анодом. При этом в катодном про- ; странстве будет получатьс  Mg(OH)., i а в анодном - серна  кислота.According to the present invention, retenu, i, proposes, in order to use the associated sulfuric acid of the uterine liquors, ground rock to undergo electrolysis with an insoluble, anode. At the same time in the cathode pro-; Mg (OH). i will be obtained in the space, and sulfuric acid in the anode one.

Дл  разложени  измельченный борат i загружаетс  в электролитическую ванну с диафрагмой в анодное пространство и -перемешиваетс  изолированной (электрически) мешалкой. В результате разложени  породы образующейс  в процессе электролиза серной кислотой часть сернокислого магин  оп ть возвращаетс  в процесс, а вместо НгЗО., образуетс  борна  кислота, обладающа  ничтожной электропроводностью и поэтому  е участвующа  в переносе электричества. На катоде образуетс  нерастворимый продукт Mg(OH)2, который можно иопользовать обычным Способом. Электролиз ведетс  с iBbicoKHM ВЫХОДОМ тока почти до ( насыщени  раствора борной кислотой. To decompose, the crushed borate i is loaded into the electrolytic bath with a diaphragm into the anode space and is stirred by an insulated (electrically) agitator. As a result of the decomposition of the rock, a part of the sulfate magne formed during the electrolysis process returns to the process, and instead of NGZO, boric acid is formed, which has negligible electrical conductivity and therefore does not participate in the transfer of electricity. An insoluble product Mg (OH) 2 is formed on the cathode, which can be used in the usual way. Electrolysis is carried out with iBbicoKHM OUT of almost current (saturation of the solution with boric acid.

Полученный раствор борной кислоты и MgSO отфильтровьгоает   от шлама, .охлаждаетс  и, после отделени  В(ОН).. на центрофуге, оп ть направл етс  в электролитическую  чейку. Расход серной кислоты, получающийс  вследствие разложени  .кальциевых пород и выпадени  гипса в осадок, пополн етс  или внесением необходимого количества серной кислоты или прибавлением сернокислого магни  в электролизер .The resulting solution of boric acid and MgSO2 is filtered off from the sludge, cooled and, after separation of B (OH) .. on a centrofuge, is again sent to the electrolytic cell. The consumption of sulfuric acid resulting from the decomposition of calcium rocks and the deposition of gypsum in the sediment is replenished by either adding the required amount of sulfuric acid or adding magnesium sulphate to the electrolyzer.

Услови  работы: катод железный, анод свинцовый или магнетитовый, плотность тока на аноде 200-500 А/м,. Температура 50-70°. Выход по току 90-95%. Аппаратура обычна , употребл ема  в аналогичных процессах.Work conditions: iron cathode, lead or magnetite anode, current density at the anode 200-500 A / m. Temperature 50-70 °. Current output 90-95%. The equipment is common, used in similar processes.

Предлагаемый способ позвол ет уменьщить расход серной кислоты на разложение боратов на 40-45% или при условии добавки MgSO совсем отказатьс  от упот реблени  серной кислоты .The proposed method makes it possible to reduce the consumption of sulfuric acid for the decomposition of borates by 40-45% or, provided that MgSO is added, to completely reject sulfuric acid.
