在浮选辉钼矿、非极性矿物及煤时使用煤油(照明煤油、拖拉机用煤油、磺化煤油及炉用煤油等),其浮选性主要由高沸点馏分的浓度(t沸点>150℃)及其结构所决定。煤油中的高分子化合物的成份愈多及在其组成中烃的亚甲基与甲基的比值(CCH_2∶CCH_3)愈大,则煤油的活性就愈高。增加煤油中的高沸点馏分的数量或高烃数量能提高其捕收性能,但由于其费用高而在经济上不合算。高能辐射的放射化学作用能改变煤油的物理
The flotation of molybdenite, non-polar minerals and coal using kerosene (lighting kerosene, tractor kerosene, sulfonated kerosene and furnace kerosene, etc.), the flotation mainly by the concentration of high-boiling point fractions (t boiling point> 150 ℃) and its structure. The more the components of the kerosene in the polymer compound and the larger the ratio of methylene to methyl (CCH_2: CCH_3) in the composition of the kerosene, the higher the kerosene activity. Increasing the number of high boiling point fractions or high hydrocarbon levels in kerosene can increase their collection performance, but is not economically justified due to their high cost. Radiochemical effects of high-energy radiation can change the physics of kerosene
