    Abstract: A process for the flotation of coarse potash ore fractions in an aqueous brine containing frother that comprises: (a) using a column flotation device in which air bubbles are generated by a sparger that utilizes high intensity shearing to mix and disperse air into brine containing frother; (b) removing a portion of the suspension at another point in the direction of flow of the suspension to regulate the upward flow rate of the suspension past the point where the air is dispersed into the suspension and thereby reducing fine particles entrainment in the froth product. The suspension can be conditioned with an aqueous composition comprising a hydrocarbon extender oil and a substantially saturated long chain primary mine, optionally comprising an acid, such as a mineral acid or carboxylic acid, to emulsify the oil in the composition, or can be conditioned with an aqueous composition comprising a long chain primary amine having an iodine value ranging from about 20 to about 70 cg/g.

    Abstract: A method for separating ash and sulfur (including pyritic sulfur) contaminants from coal in a flotation process. The method comprises the steps of grinding the coal to small particlate size, forming a slurry of the ground coal and mixing the slurry with at least one compound selected from the group consisting of peroxy compounds, peroxides and superoxides the preferred compound being oxone which is a mixture of potassium monopersulfate, potassium hydrogen sulfate and potassium sulfate. This slurry is allowed to react to condition the particulate coal and develop increased hydrophobicity for the coal while depressing the sulfur contaminants and ash during froth flotation.
