Abstract
Изобретение относитс к способам очистки флюоритового флотационного концентрата от примесей кремнезема и кальци и позвол ет повысить степень очистки, а также упростить процесс. Очистку концентрата ведут автоклавным выщелачиванием при 125-150°С водным раствором бифторида аммони при его расходе 85-95% от стехиометрии. Содержание кремнезема и кальцита в очищенном концентрате составл ет 0,1-0,2%. 1 табл.The invention relates to methods for purifying a fluorite flotation concentrate from silica and calcium impurities and allows increasing the degree of purification as well as simplifying the process. The concentrate is purified by autoclave leaching at 125-150 ° C with an aqueous solution of ammonium bifluoride at its consumption of 85-95% of stoichiometry. The content of silica and calcite in the purified concentrate is 0.1-0.2%. 1 tab.
Description
Изобретение относитс к гидрометаллургическим способам очистки концентратов и может найти применение при получении высококачественных флюоритовых концентратов .The invention relates to hydrometallurgical methods for cleaning concentrates and may find application in the preparation of high-quality fluorite concentrates.
Целью изобретени вл етс повышение степени очистки и упрощение процесса.The aim of the invention is to increase the purity and simplify the process.
Способ заключаетс в том, что очистку флюоритового концентрата ведут автоклавным выщелачиванием при 125-150°С водным раствором бифторида аммони при его расходе 85-95% от стехиометрии.The method consists in purifying the fluorite concentrate by autoclave leaching at 125-150 ° C with an aqueous solution of ammonium bifluoride at a rate of 85-95% of stoichiometry.
Пример. Флюоритовый флотоконцен трат состава, %: СаРа 94,8; СаСОз 1.0: ЗЮз 2,2, обработали в автоклаве при 140°С водным раствором бифторида аммони концентрацией 56 г/дм , что составл ет 90% от стехиометрически необходимого количества дл растворени содержащихс в концентрате кремнезема и кальцита. После выдержки в автоклаве при перемешиванииExample. Fluorite flotation concentrate waste composition,%: SaPa 94,8; CASO3 1.0: CSP 2.2, treated in an autoclave at 140 ° C with an aqueous solution of ammonium bifluoride with a concentration of 56 g / dm, which is 90% of the stoichiometrically necessary amount for dissolving the silica and calcite contained in the concentrate. After aging in the autoclave with stirring
в течение 1 ч получили продукт,содержа- щий, %: CaF297,9: СаСОзО,1: 51020,1.for 1 h, a product was obtained containing,%: CaF297.9: CAS02, 1: 51020.1.
Результаты других примеров представлены в таблице.The results of other examples are presented in the table.
При указанных параметрах способ позвол ет в одну стадию обеспечить более высокую степень очистки по сравнению с прототипом, осуществл емым в 2 стадии, т.е. способ дает возможность повысить степень очистки и исключить одну стадию обработки и тем самым упростить процесс.With these parameters, the method allows in one stage to provide a higher degree of purification compared to the prototype, carried out in 2 stages, i.e. the method makes it possible to increase the degree of purification and eliminate one stage of processing and thereby simplify the process.
