Hydrophobic Agglomeration of Fine Particles

  • Chapter
Mineral Processing and the Environment

Part of the book series: NATO ASI Series ((ASEN2,volume 43))

Abstract

This is a review of hydrophobic agglomeration methods to be used for fine particles in water suspensions. The hydrophobic interaction as a consequence of the hydrogen-bonding energy of water molecules, in the vicinity of hydrophobic particles, is discussed. The pattern of the growth of agglomerates is essentially determined by hydrodynamic forces. The thermodynamic model of both the surfactant salts and the oil droplets adhesion is based on the free energy balances. The role of binding liquid in spherical agglomeration of natural hydrophobic minerals is described. The spherical agglomeration of salt-type mineral suspensions is achieved at the critical surfactant concentration, which corresponds to the precipitation and adhesion of surfactant salt. The solubility differences of surfactant salts permit the selective separation of barite from carbonate suspension.
