Description
(54) СОБИРАТЕЛЬ ДЛЯ ФЛОТАЦИИ РУД РЕДКИХ МЕТАЛЛОВ И ОЛОВА(54) COLLECTOR FOR FLOTATION OF RARE METAL AND TIN ORE
1one
Изобретение относитс к флотационному обогащению полезных ископаемых и может бы1ь использовано на обогатительных фабриках МЦМ и ШП СССР, перерабатывающих руды редких металлов и горно-химическое сырьеThe invention relates to the flotation enrichment of minerals and can be used at the beneficiation plants MTSM and ShP USSR, processing of rare metal ores and mining and chemical raw materials.
Широко распространенным классом флотореагентов-собирателей вл ютс анионные оксигидрильные соединени f.ioA widespread class of flotation reagents is f.io anionic oxyhydryl compounds.
Эффективный собиратель несульфидных минералов - алкилгидроксамовые кислоты с радикалами нормального строени и их водорастворимые соли f2j. 5An effective collector of non-sulfide minerals is alkylhydroxamic acids with normal radicals and their water-soluble salts f2j. five
Известно применение полиалкилацетгидроксамовых кислот р уThe use of polyalkyl acetydroxamic acids is known in p
Недостатками известных алкилгидро- - ксамовых кислот вл ютс их сравнительно высокие удельные расходы и, в р де случаев, неудовлетворительна селективность действи .The disadvantages of the known alkylhydroxamic acids are their relatively high specific costs and, in a number of cases, the selectivity of action is unsatisfactory.

Пример 1. Шламы гравитационного обогащени касситеритовой руды после удалени класса 15 мкм с содержанием 0,40% Soг последовательно обрабатывают сернбй кислотой до рН 5,5 собирателем формулыExample 1. Gravitational enrichment slimes of cassiterite ore, after removing a 15 µm grade with a content of 0.40% Sog, are successively treated with sulfuric acid to pH 5.5 using a formula collector
(юр г/т) щавелевой кислотой (50 г/т) и подвергают основной флотации с дву7 м перечистками при рН 3,0 и 2,5 с получением олов нного концентрата.(yr g / t) with oxalic acid (50 g / t) and subjected to basic flotation with two 7 scrubbers at pH 3.0 and 2.5 to obtain a tin concentrate.
Достигнуто повышение извлечени олова, в концентрат на 6,1-8,0% при улучшении качества концентрата на 1,2-2,0%.Achieved an increase in the extraction of tin, in the concentrate by 6.1-8.0% while improving the quality of the concentrate by 1.2-2.0%.
Пример 2. Камерный продукт ка ьцитовой флотации перовскитовой руды обрабатывают сол ной кислотой до рН 6,5, жидким стеклом 200 г/т собирателем формулыExample 2. The chamber product of kartsite flotation of perovskite ore is treated with hydrochloric acid to pH 6.5, with liquid glass 200 g / t by the collector of the formula
(с1Нг)б-СОКНОН(s1ng) b-SOKNON
(80 г/т) и аминогидроксановой кислотой {20 г/т) i. Далее осуществл ют основную флотацию и три перечистные операции при рН 4,5-3,0. Пенный продукт - перовскитовый концентрат.(80 g / t) and aminohydroxanoic acid {20 g / t) i. Next, the main flotation and three reheating operations are carried out at a pH of 4.5-3.0. Foamy product - perovskite concentrate.
Использование предлагаемого собирател позвол ет увеличить содержание Т102 в концентрате на 2,7-3,4% приThe use of the proposed collector allows to increase the content of T102 in concentrate by 2.7-3.4% with
повьшении извлечени на 1,9-3,8% по сравнению с действием известных собирателей.extraction increase by 1.9-3.8% compared with the effect of known collectors.
Увеличение длины радикала R свышеIncreasing the length of the radical R over
СН,(и свыше 5) нецелесообразно, так как приводит к снижению растворимости собирател и ухудшению его флотационных свойств.CH, (and more than 5) is impractical because it leads to a decrease in the solubility of the collector and the deterioration of its flotation properties.
Таким образом, основное преимущество предлагаемого изобретени состоит в повьшгении технологических показателей процесса флотации руд редких металлов и олова.Thus, the main advantage of the invention is to improve the technological indicators of the process of flotation of ores of rare metals and tin.
