Description

Известен способ получени  борного концентрата из естественных рассолов путем извлечени  из этих рассолов бора гидроокисью магни  или кальци .A method is known for producing a boron concentrate from natural brines by extracting boron from these brines with magnesium hydroxide or calcium hydroxide.

Особенность описываемого способа заключаетс  в ведении процесса получени  борного концентрата из естественных рассолов с применением гидроокиси кальци  в три стадии, что дает возмол ность получать концентрат с повышенным содержанием бора.The peculiarity of the described method lies in the process of obtaining the boron concentrate from natural brines using calcium hydroxide in three stages, which makes it possible to obtain a concentrate with a high boron content.

Процесс осуществл ют следующим образом.The process is carried out as follows.

Сначала исходный рассол (например, индерскую рапу, содержащую около 0,058% В2Оз) обрабатывают известковым молоком; при этом осаждаютс  гидроокись магни  и частично бор; последующей обработкой выпавщего осадка свежим рассолом содержание В2Оз в нем доводитс  до 8-9%.First, the initial brine (for example, Indian brine containing about 0.058% of B2O3) is treated with lime milk; magnesium hydroxide and partially boron are precipitated; by subsequent treatment of the precipitated precipitate with fresh brine, the B2O3 content in it is adjusted to 8-9%.

Полученный боромагниевый концентрат повторно обрабатывают известковым молоком, при этом вследствие повыщени  рН свыще 50- 70Vo бора (из бормагниевого концентрата) переход т в раствор; содержание В2Оз в полученном растворе составл ет от 0,18 до 0,20%.The resulting boromagnesium concentrate is re-treated with lime milk, and due to the increase in pH, an excess of 50-70 Vo of boron (from bormagne concentrate) is transferred into the solution; the B2Oz content in the resulting solution is from 0.18% to 0.20%.

Раствор, содержащий от 0,18 до 0,20% В2Оз, снова обрабатывают известковым молоком при температуре около 95°, при этом осаждаютс  боркальциевый концентрат. Промытый н высушенный продукт содержит 25-30% В2Оз при степени извлечени  бора из рассола около 60%.The solution, containing from 0.18 to 0.20% B2O3, is again treated with lime milk at a temperature of about 95 °, while borcalcium concentrate is precipitated. The washed and dried product contains 25-30% of B2O3 with a degree of extraction of boron from brine of about 60%.

Расход извести на 1 т составл ет около 10 т.The consumption of lime per ton is about 10 ton.

Предмет изобретени Subject invention

Способ получени  борного концентрата из естественных рассолов, содержащих соли магни , путем обработки этих рассолов известковым молоком с осаждением бора на гидроокиси магни  в виде бормагниевого концентрата, отличающийс  тем, что, с целью повыщени  со№ 107150,The method of producing boron concentrate from natural brines containing magnesium salts by treating these brines with lime milk with boron deposited on magnesium hydroxide as bormagne concentrate, characterized in that, in order to increase the content of no. 107150,

держани  бора в конечном продукте, бор из боромагниевого концентрата перевод т в раствор обработкой его известковым молоком и полученныйпромежуточный рас,тв,щ ещераз дополнительно обрабатывают известковым молоком с въадёлерйем обогащеного бором боркальциевогр концентрата. . - holding boron in the final product, boron-magnesium concentrate boron is transferred into the solution by treating it with lime milk and the resulting intermediate mixture, further, is further treated with lime milk with boron-rich boron-enriched boron-rich milk. . -
