浮选是氧化铁矿的有效选别方法之一。目前我国用浮选法选别铁矿石的选矿厂都是采用氧化石腊皂、氧化石腊皂与塔尔油(4∶1)的混合药剂或者是粗硫酸盐皂作为捕收剂。近年来,随着钢铁工业的迅速发展,氧化铁矿浮选药剂的需要量大大增加,以松木为原料的造纸工业副产—粗硫酸盐皂或以它为原料加工成的塔尔 Flotation is one of the effective methods of sorting iron oxide. At present, China’s flotation separation of iron ore beneficiation plants are the use of oxidized paraffin wax soap, paraffin wax and tallow oil (4: 1) of the mixed agent or crude sulfate soap as a collector. In recent years, with the rapid development of the iron and steel industry, the demand for flotation reagents for iron oxide ore has greatly increased. As a by-product from crude paper made from pine wood, crude sulfate soap,
