  • Promoters for use in the anionic circuit of froth flotation of mineral ores
    Patent number: 4337149
    Abstract: An improved froth flotation process wherein preselected particles are selectively separated under froth flotation conditions as a froth phase from remaining feed particles as an aqueous phase in the presence of an anionic collector. Such improvement is characterized by the addition of an effective proportion of a promoter. The promoter is characterized as an amine oxide promoter. Preferred feed particles are phosphate ore particles.
    Type: Grant
    Filed: May 11, 1981

  • Amine oxide promoters for froth flotation of mineral ores
    Patent number: 4325821
    Abstract: Disclosed is an improved froth flotation process wherein preselected solid particles are selectively separated under froth flotation conditions as a froth phase from remaining solid feed particles as an aqueous phase in the presence of a collector amine. Such improvement comprises conducting said froth flotation in the presence of an effective proportion of an amine oxide promoter. The preferred feed particles comprise sylvinite ore.
