摘要： Fine coal is cleaned of its mineral matter impurities and dewatered by mixing the aqueous slurry containing both with a hydrophobic liquid, subjecting the mixture to a phase separation. The resulting hydrophobic liquid phase contains coal particles free of surface moisture and droplets of water stabilized by coal particles, while the aqueous phase contains the mineral matter. By separating the entrained water droplets from the coal particles mechanically, a clean coal product of substantially reduced mineral matter and moisture contents is obtained. The spent hydrophobic liquid is separated from the clean coal product and recycled. The process can also be used to separate one type of hydrophilic particles from another by selectively hydrophobizing one.
摘要翻译：通过将含有两者的含水浆料与疏水性液体混合，使混合物进行相分离，精细煤清除其矿物质杂质并脱水。所得到的疏水性液相含有不含表面水分的煤颗粒和由煤颗粒稳定的水滴，而水相含有矿物质。通过机械地将夹带的水滴从煤颗粒中分离出来，获得了基本上减少的矿物质和水分含量的干净的煤制品。将废弃的疏水性液体与清洁煤产品分离并再循环。该方法还可用于通过选择性疏水化一种亲水颗粒与另一种亲水颗粒分离。

摘要翻译：通过将含有两者的水性浆液与疏水性液体混合，使混合物进行相分离，将细煤清除其矿物质杂质并脱水。所得的疏水液相包含无颗粒表面水分的煤颗粒和由煤颗粒稳定的水滴，而水相含有矿物质。通过机械方式将夹带的水滴从煤颗粒中分离出来，获得了明显减少矿物质和水分含量的洁净煤产品。废弃的疏水液体从洁净煤产品中分离出来并循环使用。该工艺也可用于通过选择性疏水化一种亲水性颗粒与另一种亲水性颗粒进行分离。
