Description
Дл получени ZrOs за границей примен ют высокопроцентные цирконовые минералы, как-то: баделит (ZrO2), циркон (ZrSiO).To obtain ZrOs abroad, high-grade zircon minerals are used, such as: Badelite (ZrO2), Zircon (ZrSiO).
Дл переработки этих минералов примен ют либо щелочные методы, либо кислотные, причем из кислотных методов , из журнальной и патентной литературы известны сернокислотный и сол нокислотный .Either alkaline or acidic methods are used to process these minerals, and sulfuric acid and hydroacidic are known from acidic methods from the journal and patent literature.
У нас в СССР залежей высокопроцентных цирконовых минералов не имеетс , но имеютс большие запасы (до 50 млн. тонн) эвдиолитовых пород в Ловозерских тундрах, каковые после механического обогащени дают эвдиолитовый концентрат, представл ющий собой кальциево-железистый силикат циркони , имеющий следующий состав: ZrO..-в/о, TiO,-0,55, SiOz -51,82, Саб - 9,16, FejOs - 8,40.We in the USSR do not have deposits of high-grade zircon minerals, but there are large reserves (up to 50 million tons) of eudiolite rocks in the Lovozero tundras, which, after mechanical enrichment, produce eudiolite concentrate, which is calcium-ferrous zirconium silicate, having the following composition: ZrO ..- w / o, TiO, -0.55, SiOz -51.82, Sab - 9.16, FejOs - 8.40.
Суд по заграничной патентной и журнальной литературе, на практике одним из наиболее прин тых способов выделени циркони из кислых растворов (НС или ) вл етс осаждение The court in overseas patent and journal literature, in practice, one of the most accepted methods for separating zirconium from acidic solutions (HC or) is precipitation
его в виде фосфата циркони фосфорной its in the form of zirconium phosphate phosphate
J кислотой.J acid
Применение серной и сол ной кислот дл разложени эвдиолита авторы считают нецелесообразным по следующим причинам:The use of sulfuric and hydrochloric acids for the decomposition of eudiolite is considered inappropriate for the following reasons:
1) потер как так и HCI в виде1) lost both HCI in the form
(95)(95)
малоценных продуктов СаЗОч и СаС за счет СаО эвдиолитового концентрата;low-value products of SaZOCH and CaC due to the CaO of eudiolite concentrate;
2)обработка HCI эвдиолитового концентрата при нагревании крайне затрудн ет выбор материала дл аппаратуры и, наконец,2) HCI treatment of the eudiolite concentrate when heated makes it extremely difficult to choose the material for the apparatus and, finally,
3)необходимость применени фосфорной кислоты дл осаждени фосфата циркони , крайне удорожает продукт .3) the need to use phosphoric acid to precipitate zirconium phosphate, extremely expensive product.
Исход из вышеизложенного, предлагаетс новый способ переработки эвдиолитового концентрата с получением ZrO2 и норвежской селитры, заключающийс в следующем. Эвдиолит подвергают разложению избытком азотной кислоты; при этом в раствор переход т Са, Zr и Fe в виде соответствующих нитратов, оставл в остатке SiOj. Полученный азотнокислый раствор подвергаетс осаждению апатитовым концентратом с образованием фосфата циркони и норвежской селитры. Полученный фосфат циркони подвергаетс , как обычно, спеканию с содой с получением NajPOd и ZrOj, каковые раздел ютс выщелачиванием водой. /Азотнокислый раствор нитрата кальци и нитрата железа подвергаетс выправке и кристаллизации с выделением норвежской селитры, а маточный раствор подвергаетс очистке от железа и идет на вторичную обработку эвдиолитового концентрата (см. прилагаемую схему).Based on the foregoing, a new method is proposed for processing eudiolite concentrate to produce ZrO2 and Norwegian nitrate, as follows. Evdiolit decomposed with an excess of nitric acid; at the same time, Ca, Zr and Fe are transferred to the solution in the form of the corresponding nitrates, leaving SiOj as a residue. The resulting nitric acid solution is subjected to precipitation with an apatite concentrate to form zirconium phosphate and Norwegian nitrate. The zirconium phosphate obtained is subjected, as usual, to sintering with soda to obtain NajPOd and ZrOj, which are separated by leaching with water. / The nitric acid solution of calcium nitrate and iron nitrate undergoes straightening and crystallization to liberate Norwegian nitrate, and the mother liquor is purified from iron and is recycled to the eudiolite concentrate (see the attached diagram).
