FIELD: soil or rock drilling; mining.
SUBSTANCE: invention relates to concentration of minerals by flotation and can be used in coal flotation. Use of the composite reagent of the following composition: unsaturated hydrocarbons 55–60 wt. %, dioxane alcohols and esters thereof 24–26 wt. %, ketones 6–10 wt. %, aromatic compounds 5–6 wt. %, aldehydes and alcohols 2–3 wt. % as reagent for coal flotation.
EFFECT: technical result is improved technological effectiveness of coal flotation process, high output of concentrate while reducing consumption of composite reagent by two times and high efficiency of process.
