Abstract: A method for enhancing hydrophobicity of high volatile bituminous coal and coals of a lower grade and for separating ash and sulfur (including pyritic sulfur) contaminants from coal in a floatation process. The method comprises the steps of grinding the coal to small particulate size, forming a slurry of the ground coal and mixing the slurry with at least one compound selected from the group comprising inorganic peroxy compounds, 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.

Abstract: Dialkyl xanthogen formates are known collectors, but the reaction that produces them, between an alkaline alkyl xanthate and an alkaline chloroformate, also causes side reactions which produce varying amounts of xanthic anhydride, carbonyl sulfide and dialkyl carbonate as by-products, and yield of formate may be as low as 30%. There are here disclosed processing schemes for controlling the amount and type of products and by-products produced in the reaction, and flotation tests show that certain product mixtures are significantly improved collectors for sulfide ores.
