    Abstract: Homogeneous liquid cationic compositions are produced by combining one or more cationic agents with one or more compounds of the formula HO(X--O).sub.x --R--(O--Y).sub.y --OH wherein each X is ethylene, straight or branched propylene, or straight or branched butylene; x is 0 to 40; each Y is ethylene, straight or branched propylene, or straight or branched butylene; y is 0 to 40; the sum of (x+y) is 0 to 40; and R is saturated straight, branched or cyclic alkylene containing 4 to 12 carbon atoms or, if (x=y=0), R contains 7 to 12 carbon atoms. Compositions are easily dispersed in water, even at room temperature, at any concentration and can be made to form clear or translucent products having a desirable uniform appearance, by appropriate selection of components and their amounts.

    Abstract: Disclosed is a process for the concentration of sulfide ore wherein an aqueous slurry of sulfide ore particles are subjected to sulfide ore froth flotation under sulfide ore froth flotation conditions. The improvement in process comprises using an effective amount of a frothing agent selected from the group consisting of:(a) the reaction product of a C.sub.5 -C.sub.10 diol and a C.sub.1 -C.sub.7 carboxylic acid;(b) the reaction product of a C.sub.5 -C.sub.10 diol and an acrylonitrile;(c) the reaction product of a C.sub.2 -C.sub.4 alkylene oxide and a C.sub.1 -C.sub.7 carboxylic acid;(d) the reaction group of a C.sub.2 -C.sub.4 alkylene oxide and a C.sub.5 -C.sub.10 diol;(e) the reaction product of a C.sub.2 -C.sub.4 alkylene oxide and an acrylonitrile; and(f) mixtures thereof,the resulting modified alcohol frothing agents have at least one hydroxyl group thereon. The modified alcohol frothing agents of the present invention provide improved flotation kinetics and selectivity in the sulfide ore float.

    Abstract: Disclosed is an improved froth flotation process wherein solid coal particles are selectively separated under coal froth flotation conditions as a froth phase from remaining solid feed particles as an aqueous phase in the presence of a coal particle collector (e.g. a fuel oil), optionally a promoter, and an alcohol frother. The improvement in the present invention is characterized by the alcohol frother comprising the reaction product of a C.sub.4 -C.sub.10 diol and a compound selected from the group consisting of an alkylene oxide and an acrylonitrile. The resulting frothing agent has at least one hydroxyl group and provides greater coal recovery than use of the diol as the frothing agent.
