非极性油(烃油)作为非极性矿物——煤、硫、石墨、辉钼矿的捕收剂早已被应用在浮选中。曾经指出,在浮选辉钼矿石时,较粘滞的烃油使辉钼矿和脉石连生体有较高的回收率,并且较少地使泡沫破灭。不久前曾查明,烃油对经黄药处理过的硫化矿物表面的作用和对非极性矿物一样。因此,建议在用黄药浮选硫化矿时,添加烃油以提高粗颗粒以及矿石矿物和脉石的连生体在泡沫产品中的回收率。不仅非极性油的粘度,而且它的组成,也具有重 Non-polar oil (hydrocarbon oil) as a non-polar minerals - coal, sulfur, graphite, molybdenite collector has long been used in flotation. It has been pointed out that in the flotation of molybdenite, the more viscous hydrocarbon oil gives a higher recovery of the molybdenite and gangue strands and the less foam bursts. Not long ago it was ascertained that the effect of hydrocarbon oils on the surfaces of xanthogenated sulphide minerals is the same as for non-polar minerals. Therefore, it is advisable to add hydrocarbon oil to the flotation of sulphide ore with xanthate to increase the recovery of coarse particles and concatenation of ore minerals and gangue in the foam product. Not only the viscosity of the non-polar oil, but also its composition, also has a heavy weight
