APPLICATION OF A TECHNICAL PRODUCT OF PETROCHEMICAL PRODUCTION OF A GRADE A RAW DESICCANT AS A FOAMER FOR COAL FLOTATION Russian patent published in 2022 - IPC B03D1/16 B03D1/02 

FIELD: mineral processing.

SUBSTANCE: invention relates to the field of mineral processing and can be used in coal-cleaning plants during coal flotation. As a foaming agent for coal flotation, a raw desiccant of the A grade is used. At the same time, the A grade raw desiccant contains 45-50% ethyl ether of triethylene glycol (EETEG), 33-35% diethylene glycol, 0.6% ethylene glycol (EG), 0.2% ethyl cellosolve, 0.2% moisture and 16-19% of the remaining components of the production cycle in the form of triethylene glycol (TEG), ethyl ethers of diethylene glycol (EEDEG) and tetraethylene glycol (EETetraEG).

EFFECT: increase in the selectivity of the coal flotation process and an increase in the extraction of the combustible mass into the concentrate.
