Title:
FLOTATION OF PARTICLES BY CHEMICALLY-INDUCED SPARGING OF BUBBLES
Document Type and Number:
WIPO Patent Application WO/2012/173661
Kind Code:
A8
Abstract:
A method and apparatus in accordance with the present invention comprising a decomposable compound such as hydrogen peroxide as a primary additive to generate bubbles within a fluid medium such as an aqueous slurry of tar sands. The size range of bubbles, density (number per unit volume) of bubbles, and rate of in situ generation of bubbles are controlled by controlling process variables including but not limited to temperature, concentration of decomposable compound, residence time, pressure, viscous shear, ratio of water to solids, pH of the slurry, shape of the separation vessel, and addition of one or more secondary process additives.
