  Sodium Benzoate and Urea as Promoters in Sillimanite Flotation

  By Mihir D.M., Rama Rao V.V, Padmasree R.

  Abstract: Sillimanite is an alumino-silicate mineral with the chemical formula Al2SiO5. Sillimanite in general is concentrated by gravity separation methods followed by froth flotation. Hydrophobicity is induced to sillimanite surface by adsorbing surfactant (oleic acid/oleate) molecules selectively and the mineral is collected into froth as concentrate. Other reagents used are; sodium silicate to depress garnet and silica and sodium hydroxide to adjust the pulp pH. In the present study, hydrotropes (sodium …
