Description

Борные заводы перерабатывают индерские ашаритовые бораты на борную кислоту сернокислотным способом. Дл  успешного р зложени  указанногосырь  нужно вести процесс в кислой среде с пол чением растворов дл  кристаллизации борной кислоты, содержащих некоторое количество свободной серной «ислоты. Между тем индсрское месторождение боратов содержит р д более легко разложилппх минералов, дл  разложени  которых предлагаетс  следующа  схема.Boric plants process Indian acid asharic borates for boric acid using the sulfuric acid method. For successful decomposition of the above, it is necessary to conduct the process in an acidic medium with the preparation of solutions for the crystallization of boric acid containing some amount of free sulfuric acid. Meanwhile, the Indian borate deposit contains a number of more easily decomposed minerals, for which the following scheme is proposed.

Борат разлагаетс  не пол;ши:и количествами кислоты в пределах от К) до 50% от стехиометрической -нормы в ш,елочной среде. Щелочную пульпу фильтруют и полученный щелочной раствор перед фильтрованием через «чистый фильтр или после «чистого фильтра в кристаллизаторе подкисл етс  кислотой, после чего из него кристаллизуетс  борна  кислота.Borate does not decompose sex; shi: and amounts of acid in the range from K) to 50% of the stoichiometric-norm in a Christmas tree environment. The alkaline pulp is filtered and the resulting alkaline solution is acidified with acid before the filtration through the "clean filter or after" the clean filter in the crystallizer, after which boric acid crystallizes.

Предлагаема  схема дает значительную экономию серной кислоты и увеличение выходов борной кислоты благодар  незначительному разлон-аению .магниевых соединений боратовой породы п возможности , вследствие того, возвр.ащать маточники в процесс..The proposed scheme provides significant savings in sulfuric acid and an increase in the yields of boric acid due to a slight dilution of magnesium compounds of borate rock and the possibility, due to the return of mother liquors to the process ..

Предлагаемый способ имеет большое значение дл  переработки бедных индерских гидроборацитовых боратов, использование которых дает возможность резко увеличить сырьевую базу боратов.The proposed method is of great importance for the processing of poor Indian hydrobromocyte borates, the use of which makes it possible to dramatically increase the raw material base of borates.

Предмет изобретени Subject invention

1. Способ получени  борной кислоты из магнезиальных боратон путем КИСЛО.ТНОГО разложени  1юследних, отличающийс  тем, что, с целью умен,ьи1ен,и  р,асхода кислоты и снижени  перехода в раствор соеди;н.ений магни , исходное сырье обрабатывают не полны :ми количествами кислоты в предел-ах от 10 до 50% от сте.х-иометричеJ o 6 8G3- 2 -1. A method of producing boric acid from magnesian boraton by acidic acid decomposition of the latter, characterized in that it is intelligent for the purpose of reducing acid conversion and reducing the transition to a solution of magnesium; magnesium raw materials are not completely processed: mi quantities of acid in the limit-from 10 to 50% of the EH-isometric J o 6 8G3-2 -

iKoit ;io)Mb(, после чего выдел ют борную кислоту из растворов известным образом.iKoit; io) Mb (and then boric acid is separated from the solutions in a known manner.

2. Прием выполнени  способа, согласно п. 1, отличающийс  тем. что кеобходимую дл  разложени  сырь  серную кислоту ввол т в кульпу последовательно в несколько приемов.2. Acceptance of the method according to claim 1, characterized in that. What is needed for the decomposition of the raw material, sulfuric acid is drawn into the cult consistently in several stages.
