Description
(54) ВСПЕНИВАТЕЛЬ ДЛЯ ФЛОТАЦИИ УГЛЯ(54) SPRAYER FOR COAL FLOTATION
Изобретение касаетс обогащени полезных ископаемых методом флотации.This invention relates to mineral processing by flotation.
В современной практике флотационного обогащени широко используютс смеси апол рных реагентов и поверхностно-активных соединений (вспенивателей ) в различных соотношени х в зависимости от свойств флотируемых углей .In modern practice of flotation concentration, mixtures of apolar reagents and surface-active compounds (blowing agents) are widely used in various ratios depending on the properties of floatable coal.
Широко примен етс в качестве вспе нивател реагент Т-66, представл ющий собой в основном смесь диоксановых и пирановых гетероциклических спитов 1 . Процесс флотации угл с использованием реагента Т-66 в смеси с керосином характеризуетс сравнительно высоким расходом реагентов и недостаточной селективностью. ПриThe T-66 reagent, which is mainly a mixture of dioxane and pyran heterocyclic spit 1, is widely used as a supervisor. The process of coal flotation using T-66 reagent mixed with kerosene is characterized by relatively high consumption of reagents and insufficient selectivity. With
этом образуетс обильна высокоустойчива пена.This produces a rich, highly resistant foam.
Известно применение дл флотации угл кремнийорганических жидкостей марки ПФМС 2 . Однако, применение их не позвол ет достичь достаточно высокие технологические показатели.It is known the use for flotation of carbon silicone fluids brand PFMS 2. However, their use does not allow achieving sufficiently high technological indices.
Известны полигалоидорганосилоксаны 3, используемые в газожидкост-ной хроматографии и ранее при флотации не примен вшиес .Polyhalide organosiloxanes 3 are known, used in gas-liquid chromatography and not previously used in flotation.
Цель изобретени - повысить технологические показатели процесса флотации углей.The purpose of the invention is to improve the technological performance of coal flotation.
Поставленна цель достигаетс применением в качестве вспенивател полигалоидорганосилоксанов формулыThe goal is achieved using polyhaloorganosiloxanes of the formula
1,4 - 1,6 г/см, молекул рный вес 950-1100, температура выкип. 220300°С .1.4-1.6 g / cm, molecular weight 950-1100, discharged temperature. 220300 ° C.
Вспениватель испытан при флотации угл зольностью 18,9% в смеси с тракторным керосином в соотношении 1:99 в сравнении с действием смесей с Т-66 и керосина с полиоргансилоксаном .The blowing agent was tested during flotation with 18.9% coal ash mixed with tractor kerosene in a ratio of 1:99 compared with the effect of mixtures with T-66 and kerosene with polyorganosiloxane.

Результаты испытаний показывают, что рекомендуемый вспениватель позвол ет снизить зольность концентрата на 1% при повышении выхода его на 3%.The test results show that the recommended blowing agent reduces the ash content of the concentrate by 1% while increasing its yield by 3%.
Таким образом, основное преимущество изобретени состоит в повышении технологических показателей флотации углей,Thus, the main advantage of the invention is to improve the technological performance of coal flotation,
