Description
(54) СОБИРАТЕЛЬ ДЛЯ ФЛОТАЦИИ СУЛЬФИДОВ ИЗ ЦИАНИСТЫХ ПУЛЬП(54) COLLECTOR FOR FLOTATION OF CYLYSTIC SULFIDES
Изобретение относитс к обогащению руд цветных и бпагородных металлов флотацией. При выщелачивании благородных металлов из руд, например сульфидных, а также при селективной флотации руд цветных металлов широко примен ютс цианиды. Дальнейша флотационна переработка руд с при менением известных сульфгидридных собира телей из цианистых сред затруднена вследствие образовани на поверхности сульфидов цианистого комплекса . Известно применение дл флотации сульфидов из цианистых пульп бутилового ксантогената кали | 2j. Однако этот собиратель недостаточно эффективно извлекает сульфиды. Цель изобретени -.повышение технологических показателей процесса флотации сульфидов, в том числе сульфидов, содернжащих благородные металлы, из цианистых пульп. Это достигаетс применением в качестве собирател 2-метилхинолина формулы СОУказанный собиратель может быть использован взамен известного без изменени всего реагентного режима. П D и М е р. Флотируют хвосты цианировани руды, содержащие сульфиды с заключенными в них благородными металлами, не растворившимис при цианировании. Анализ провод т на золото и серебро, как наиболее ценные в данном случае продукты. Содержание золота и серебра в исходной руде соответственно О,78 и 26,82 г/т. При флотации используют бутиловый ксантогенат кали или 2-метилхинолин и вспениватель. В результате применени 2-метилхинолина в качестве собирател сульфидов достигнуто увеличение извлечени золота на 10% и сепебра на 26% при одновременном У11учшении качества концентратов.The invention relates to the enrichment of ores of non-ferrous and bporodnykh metals by flotation. Leaching of noble metals from ores, for example, sulfide metals, as well as the selective flotation of non-ferrous metal ores, cyanides are widely used. Further flotation processing of ores using the known sulfhydride collectors from cyanide media is difficult due to the formation of a cyanide complex on the surface of sulfides. Known to use for the flotation of sulfides from cyanide pulps butyl potassium xanthate | 2j. However, this collector does not effectively remove sulfides. The purpose of the invention is to increase the technological parameters of the process of flotation of sulphides, including sulphides, containing noble metals, from cyanide pulps. This is achieved by using the formula 2-methylquinoline as collector. The CO-mentioned collector can be used instead of the known one without changing the whole reagent mode. P D and MER. Tails of cyanidation of ore containing sulphides with noble metals enclosed in them, which have not dissolved during cyanidation, are floated. The analysis is carried out for gold and silver, as the most valuable products in this case. The content of gold and silver in the original ore, respectively, O, 78 and 26.82 g / t. In flotation, butyl potassium xanthate or 2-methylquinoline and a blowing agent are used. As a result of the use of 2-methylquinoline as a collector of sulphides, an increase in gold extraction by 10% and separ by 26% was achieved while simultaneously improving the quality of concentrates.
Таким образом, основное преимущество предпагаемого тюооретени состоит в повь шении технологических показателей сульфидов, в том чиста сульфидов, сопержаших благородные металлы, из цианистых пульп,Thus, the main advantage of the predicted chiorethenium consists in an increase in the technological indicators of sulphides, including sulphides containing noble metals, of cyanide pulps,
