Froth Flotation Process Coal Beneficiation

A method is described for recovering coal from a coal ore containing coal and non-combustible mineral matter which comprises the step of floating coal in a frothing aqueous medium containing an oxygen containing compound of the formula: rsub 1--rsub 2 wherein rsub 1 and rsub 2 are independently saturated hydrocarbyls the oxygen containing compound being present in the medium in an amount effective to selectively concentrate the coal in the froth.
