Description
Изобретение относитс к металлур гии, а.конкретно к области металлотермических процессов.The invention relates to metallurgy, and specifically to the field of metallothermic processes.
Известен магниетермический способ восстановлени борного ангидрида, примен емый дл получени бора.при котором измельчённый борный ангидрид смешивают с порошкообразным металлическим магнием и провод т восстановление в открытой атмосфере. Образующиес при восстановлении бораты магни .удал ют из спека кислотным выщелачиванием .A known magnesium method of reducing boric anhydride used to obtain boron. In which the crushed boric anhydride is mixed with powdered metallic magnesium and reduced in an open atmosphere. The magnesium borates formed during the reduction are removed from the cake by acid leaching.
К недостаткам данного способа следует отнести низкое извлечение бора из борного ангидрида,в конечный продукт , вследствие окислени магнид и восстановленного бора кислородом воздуха .The disadvantages of this method include the low boron extraction from boric anhydride, to the final product, due to the oxidation of magnesium and reduced boron with oxygen from the air.
Наиболее близким к изобретению по технической сущности к достигаемому результату вл етс способ получени бора, включающий магниетермическое восстановление борного ангидрида без доступа воздуха и последующее кислотное выщелачивание спека 2.The closest to the invention to the technical essence of the achieved result is a method of obtaining boron, including the magnesium reduction of boric anhydride without air and the subsequent acid leaching of SPEC 2.
К недостаткам данного способа получени бора следует отнести сложность- технологического процесса, .св занную с необходимрс±ью осуществл ть его в вакууме или в инертной атмосфере и низкий выход продукта (максимум 85%) .Целью изобретени вл етс повышение выхода продукта и упрощение процесса.The disadvantages of this method of obtaining boron include the complexity of the technological process associated with the need to perform it in a vacuum or in an inert atmosphere and low product yield (maximum 85%). The purpose of the invention is to increase the yield of the product and simplify the process.
Поставленна цель достигаетр тем, что согласно способу получени бо-, ра, включающему магниетермическое The goal is achieved by the fact that, according to the method of producing bo-, p, including magnesium-thermal
10 восстановление борного ангидрида и последующее кислотное выцелачивание, при чем магниетермическое восстановление ведут в присутствии углерода в количестве 0,15-2,0 мас.%.10 the reduction of boric anhydride and the subsequent acid leaching, whereby the magnesium-thermal reduction is carried out in the presence of carbon in an amount of 0.15-2.0 wt.%.

.Добавки углерода к смеси борного ангидрида с магнием, привод т к существенному увеличению извлечени бора из борного ангидрида и позвол ют проводить процесс восстановлени Additions of carbon to a mixture of boric anhydride with magnesium, lead to a significant increase in the extraction of boron from boric anhydride and allow the reduction process
20 на воздухе, что упрощает процесс.20 in air, which simplifies the process.
