AQUEOUS COMPOSITION USEFUL IN ORE FLOTATION CONTAINING ALIPHATIC AMINE, EXTENDER OIL, AND EMULSIFIER

摘要

A composition, adapted to be used in the flotation ofore fractions in aqueous suspension, consists essentially of:(a) water; (b) a hydrocarbon extender oil, preferably onehaving a low aromatics content; (c) a long chain aliphaticamine, such as a tallow-based amine, preferably one with aniodine value is less than about 20 cg/g; and (d) an acidemulsifier. This composition is prepared by the followingsuccessive steps: (a) dissolution of the amine in the oil atan elevated temperature, (b) addition of the acid to theaqueous phase, (c) addition of the oil containing the amineto the aqueous phase, and (d) emulsification of the mixtureusing an appropriate shearing.
