Abstract
An improvement is disclosed applicable to systems where a mineral ore, such as a crude kaolin is introduced into a high shear, high energy mixing device with a suspending fluid and dispersing agents added to the same mixing device at controlled rates to produce a suspension with a solid content not more than 72% by weight. The process is applicable to systems where inorganic materials are suspended in a slurry, using water as the suspending fluid, in the presence of a dispersing agent, as for example in the processing of kaolin clay where the crude clay is formed into an aqueous suspension for the purpose of removing impurities and further processing. Heat is applied to the fluids in or before entering the mixing zone of the mixer, in sufficient quantity to raise the temperature of the suspension by at least 10.degree. C. This lowers the flow resistance of fluids in the mixing zone. In consequence less energy is required per unit of material processed, and more material may be processed in a given mixing unit. The heat may be added by several different methods, both directly and indirectly.
