烃类可分为脂肪烃、脂环烃和芳香烃三类。它们的特点是分子中的碳氢原子都通过共价键结合,难溶于水,不电离,故又称为非极性捕收剂。通常用作捕收剂的烃类油有煤油、变压器油、太阳油、焦油等。烃类油捕收剂主要用于浮选表面疏水性大、天然可浮性好的辉钼矿、煤、石墨、硫和滑石等,也可作为其它矿物浮选的辅助捕收剂,其捕 Hydrocarbons can be divided into aliphatic hydrocarbons, alicyclic hydrocarbons and aromatic hydrocarbons three categories. They are characterized by the molecular hydrogen atoms are covalent bonds, insoluble in water, do not ionize, it is also known as non-polar collector. Hydrocarbon oils commonly used as collectors include kerosene, transformer oil, sun oil, tar and the like. Hydrocarbon oil collector is mainly used for the flotation surface of hydrophobic, natural floatability molybdenite, coal, graphite, sulfur and talc, but also as a secondary mineral flotation collector, the capture
