Description

Изобретение относитс  к обогащению полезных ископаемых и может быть использовано при флотации угл  и графи- та, . The invention relates to the enrichment of minerals and can be used in the flotation of coal and graphite.

Цель изобретени  - повышение селективности процесса флота ции.The purpose of the invention is to increase the selectivity of the flotation process.

.Способ флотации заключаетс  в том, что при кондиционировании в качестве вспенивател  ввод т монотретичный бутиловый эфир этиленгликол  формулыThe flotation process consists in the introduction of mono-tert-butyl ether of ethylene glycol of the formula

In coal flotation, the use of ethylene glycol mono-tertiary butyl ether compared to diethylene glycol di-tertiary butyl ether (a known method) reduces the ash concentration of the coicentrate from 8.83 to 7.20% and increases ash content of waste from -60.65 to 74.8%; for graphite flotation to reduce the ash content of the concentrate
