FIELD: concentration of non-sulfide ores; concentrating mills for selective separation of feldspars.
SUBSTANCE: proposed method of selective floatation of non-sulfide ores is performed by cation-type collecting agents in presence of acid regulator of hydrofluoric acid. Used as cation-type collecting agent are primary distilled amines of C10-14 fraction. Used as acid regulator is waste of production of hydrofluoric acid, that is mixture of hydrofluoric and hydrochloric acids containing, mass-%: hydrofluoric acid, 32-42 and hydrochloric acid, no more than 15.
EFFECT: improved technological parameters; low cost of process.
