    • 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.
    • 一种提高高挥发性烟煤和较低级煤的疏水性的方法,用于在浮选过程中从煤中分离灰分和硫(包括黄铁矿硫)污染物。 该方法包括以下步骤:将煤粉碎成小颗粒尺寸,形成研磨煤的浆料,并将浆料与至少一种选自无机过氧化合物的化合物混合,优选的化合物为氢氧化钾,其为钾 单硫酸盐,硫酸氢钾和硫酸钾。 允许该浆料反应以调节颗粒状煤并且在泡沫浮选期间抑制硫污染物和灰分时,对煤产生增加的疏水性。
