FLOTATION OF THE COAL OXIDE WITH SODIUM POLYACRYLATE LATEX EMULSION

摘要

Disclosed is a treating agent and method for increasing the yield of oxidized carbon or carbon when concentrating carbon particles by foam flotation. /P P As a promoter or as a foaming aid, a sodium polyacrylate latex is used at a rate of 8.5 to 250 g of dry sodium polyacrylate per tonne of dry carbon. The preferred promoter is a sodium polyacrylate water-in-oil latex, preferably used with an alcohol-type foamer. The latex can be used neat and self-reverse with the help of an oil-in-water surfactant and water, forming an oil-in-water emulsion or it can be used. as a two-part system with an aqueous activator to allow reversal. /P P Particular application to the flotation of coal mined in the open air.
