Coal Froth Flotation: Effects of Reagent Adsorption on the ...

Abstract. The −53 μm size fraction of a bituminous coal was used to perform froth flotation experiments. The froth flotation of the coal used was performed in the presence of two nonionic surfactants, Triton x100 (poly (ethylene glycol) tert octylphenyl ether) and MIBC (methyl isobutyl carbinol), and an .
