FIELD: mining industry.
SUBSTANCE: invention relates to flotation concentration of non-sulfide ores, in particular fluorite ores. Process of invention comprises flotation involving various modifiers and use of oleic acid/2-aminoethanol mixture (molar ratio close to 1:1) as collector. Use of indicated mixture allows conduction of basic flotation without heating of pulp, recovery of fluorite increased by 4.6%, and reduction of harmful calcite content in preliminary concentrate by 2%.
EFFECT: enhanced process efficiency.
