Description
Насто щее изобретение имеет целью переработку боросодержащих руд на борную кислоту с одновременным использованием реагентов и всех составных частей сырь .The present invention aims to process boron-containing ores into boric acid while simultaneously using reagents and all the constituents of the feedstock.
Согласно новому способу боросодержащую руду обрабатывают азотной кислотой при нагревании, полученный раствор, состо щий в основном из азотнокислых солей и борной кислоты, отфильтровывают от нерастворимого остатка или после отстаивани декантируют. Из полученного фильтрата после охлаждени выкристаллизовывают борную кислоту, которую отдел ют от маточного раствора, а последний снова возвращают в процесс вместо воды дл разложени свежей порции руды.According to the new method, the boron-containing ore is treated with nitric acid with heating, the resulting solution, consisting mainly of nitric acid salts and boric acid, is filtered off from the insoluble residue or decanted after settling. After cooling, boric acid crystallizes out of the obtained filtrate, which is separated from the mother liquor, and the latter is returned to the process instead of water to decompose a fresh batch of ore.
К полученному в результате 3 - 4 заворотов маточному раствору, содержащему около 4% борной кислоты, прибавл ют небольшое количество известн ка или известкового молока. В результате такой обработки почти вс оставша с в растворе борна кислота выпадает в осадок в виде борокальцита, который отфильтровывают и снова ввод т в процесс дл разложени азотной кислотой.A small amount of lime or milk of lime is added to the resulting 3–4 turns of the mother liquor containing about 4% boric acid. As a result of this treatment, almost all of the boric acid remaining in the solution precipitates as borocalcite, which is filtered and re-introduced into the process to decompose with nitric acid.
Маточный раствор, состо щий в основном из азотнокислых солей кальци и магни , может быть переработан различнь1ии способами.The mother liquor, consisting mainly of calcium and magnesium nitrate salts, can be processed in various ways.
№9)№9)
По первому из способов маточный раствор упаривают и кристаллизуют;; получаетс высококачественное удобрение , содержащее азот, Мд,Са и cлeдь, бора.According to the first method, the mother liquor is evaporated and crystallized ;; A high-quality fertilizer containing nitrogen, MD, Ca, and C, boron is obtained.
По второму способу, маточный раствор обрабатывают раствором содыили потаща, причем Са и Мд выпадают в осадок в виде смеси углекислых солей чрезвычайно тонкого порошка белого цвета.In the second method, the mother liquor is treated with a solution of soda or sweating, and Ca and Md precipitate as a mixture of carbonate salts of an extremely fine white powder.
Углекислые соли отфильтровывают и высушивают, а фильтрат упариваюти кристаллизуют, причем, в зависимости от того, кака углекисла соль былгь вз та дл осаждени , получаетс либо натронна либо калийна селитра.The carbonated salts are filtered and dried, and the filtrate is evaporated and the crystals are crystallized, and depending on whether the carbonate salt is taken up to precipitate, either soda or potassium nitrate is obtained.
Выход борной кислоты составл ет 98,5%.The boric acid yield is 98.5%.
