  • Silica flotation collectors derived from isononyl alcohol
    Patent number: 4422928
    Abstract: This invention relates to the use of a primary-branched aliphatic ether monoamine, 3-nonyloxypropylmonoamine, its ethoxylated or propoxylated derivatives and partial acid salts thereof, as a major or minor constituent in the formulation of superior silica flotation collectors. Such collectors are employed in the separation of silica from iron ore, phosphate, and other valuable ores.
    Type: Grant
    Filed: September 17, 1982
    Date of Patent: December 27, 1983
    Assignee: Exxon Research & Engineering Co.

  • Branched alkyl ether amines as iron ore flotation aids
    Patent number: 4319987
    Abstract: The use of primary aliphatic ether amines as silica collectors in the concentration of minerals by the froth flotation process. More specifically, the use of mixtures of primary methyl branched aliphatic ether amines and the partially-neutralized salts thereof as flotation reagents. In further aspect, the use of mixtures of 3-isooctoxypropyl monoamine and 3-isodecoxypropyl monoamine and/or the partially-neutralized acetate salts thereof as collectors for silica in the beneficiation of oxidized taconite ores.
