Description
Известны реагенты-вспениватели при флотационном обогащении полиметаллических руд, например сосновое масло при медной флотации медно-цинковой пиритнсй руды и,крезол при свинцово-медной флотации свинцово-медно-цинковой руды.Known reagents are blowing agents for flotation concentration of polymetallic ores, for example, pine oil for copper flotation of copper-zinc pyrite ore, and cresol for lead-copper flotation of lead-copper-zinc ore.
Предлагаемое применение в качестве реагента-вспенивател полиэтиленгликолей состава НО-(-СН2СН2ОСН2СН2-)-ОН получаемых конденсацией с водой этиленгликолей или окиси этилена, в том числе кубовых остатков производства моно-, ди- и триэтиленгликолей из продуктов гидратации окиси этилена, позвол ет улучшить при флотации качество концентратов и заметно повысить извлечение цинка из полиметаллических руд.The proposed use as a foaming agent of polyethylene glycols of the NO - (- CH2CH2OCH2CH2 -) - OH composition obtained by condensation of ethylene glycols or ethylene oxide with water, including bottoms of the production of mono-, di- and triethylene glycols from the products of ethylene oxide hydration, improves the flotation quality concentrates and significantly increase the extraction of zinc from complex ores.
При этом кубовые остатки этиленгликолей, как установлено опытами , в отличие от известных реагентов вл ютс более селективным вспенивателем .At the same time, the residues of ethylene glycols, as established by experiments, in contrast to the known reagents, are a more selective foaming agent.
Предлагаемый реагент опробован на флотации дегт рских и зыр новских руд и дал положительные результаты.The proposed reagent was tested on flotation of tar and zyrovsk ores and gave positive results.
