Flotation of coal with latex emulsions of hydrocarbon animal or vegetable based oil
Patent
·
OSTI ID:7051924
Employment of a latex emulsion prepared from a hydrocarbon, animal or vegetable based oil with a hydrophobic water-in-oil emulsifier and a hydrophilic surfactant in the froth flotation of coal improves coal recovery without increasing the ash content. The emulsifier employed should have an hlb value of 5.0 or less while the surfactant should have an hlb value of 9.0 or higher.
