    Abstract: The invention is a process for recovering coal or mineral values from raw coal or mineral ore which comprises subjecting the raw coal or mineral ore in the form of an aqueous pulp, to a floatation process in the presence of a floatation collector, and a flotating amount of a floatation frother which comprises the reaction product of an alitphatic C.sub.6 alcohol and between about 1 and 5 moles of propylene oxide, butylene oxide or mixtures thereof, under conditions such that the coal or mineral values are recovered.

    Abstract: A phosphate ore fllotation process subjects a phosphate ore containing silica and silicates to froth flotation in the presence of a collector, said collector being a C.sub.36 high molecular weight dibasic acid comprising two carboxylic functional groups, recovering the phosphate concentrate from the overflow, and removing the separated silica and silicates in the underflow. The dibasic acids should be used in conjunction with fuel oil, not only to reduce the reagent consumption, but also to increase the grade and recovery of phosphate concentrate. The selectivity of some of these collectors is so great than an acceptable phosphate rock concentrate can be obtained from the phosphate ore in a single anionic circuit.

    Abstract: A process is provided for the flotation of ores, wherein esters of orthophthalic acid or maleic acid with C.sub.8 -C.sub.14 alcohols or oleyl alcohol are used as collectors, together with the usual fatty acid type collectors, thus permitting important savings in the use of this latter component. Particular advantages are so obtained in the flotation of phosphate ore and of magnesium-containing minerals.
