FIELD: chemistry.
SUBSTANCE: method involves preparation of a suspension and its gravitational concentration. For selective extraction of finely dispersed mono-mineral fractions, polyacrylic acid salts containing 10-120 mono-mineral links or alkylnaphthalene sulfoacid modified with formaldehyde and containing 2-8 monomineral links are added in amount less than 2.5% of the weight of the solid phase of the suspension. The alkyl used is butyl or isobutyl.
EFFECT: more efficient separation of polymineral finely dispersed suspensions with particle size less than 40 micrometres.
