Silica Flotation Monoamine

Silica flotation collectors derived from isononyl alcohol

More particularly, it relates to the use of 3-nonylpropyl-monoamine and partial acid salts as cationic flotation collectors in froth flotation of silica. BACKGROUND OF THE INVENTION. Froth flotation is a common process applied to the art of separating or concentrating minerals from ore or the like.

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.

Effect of collector, pH and ionic strength on the cationic

2009-9-1  In distilled water, ether diamine, a strong collector for silica, does not induce any flotation or only very weak flotation of kaolinite over a wide pH range from pH 3 to pH 10.5. Ether monoamine causes strong flotation of kaolinite in distilled water, especially in acidic solutions, but high dosages of the collector are required.

Effect of collector, pH and ionic strength on the cationic

Ether monoamine causes strong flotation of kaolinite in distilled water, especially in acidic solutions, but high dosages of the collector are required. Such observations are in contrast to the flotation behaviour of oxide minerals such as silica for which ether diamine shows stronger collecting power than ether monoamine.

Branched alkyl ether amines as iron ore flotation aids

The ether monoamine collectors of the invention are by nature cationic surfactants. The amino groups (--NH 2) attach to silica and silica materials, providing the required selectivity for flotation, while the ether linkages (R--O--C) give these materials relatively low melting points and good dispersibility. Although useful in free amine form
