Document Type and Number:
Japanese Patent JPS6255901
Kind Code:
B2
Abstract:
The froth flotation of coal in the presence of a condensate of an alkanolamine with at least about 0.8 equivalent of a fatty acid improves the separation of carbonaceous solids possessing relatively high heat value from ash and other inert mineral matter. Flotation in the presence of this condensate is particularly effective to enhance the recovery of oxidized bituminous coal.
