氧化矿捕收剂的增效剂

SYNERGISTSFOR COLLECTORSOF OXIDE ORES

工业上广泛应用的氧化矿捕收剂仍以脂肪酸类、黄药类及其衍生物为主 ,羟肟酸也是一类成功的捕收剂 .增效剂的引入可改善捕收剂的性能 .用一些本身具有一定捕收剂功能的药剂 ,或者毫无捕收剂性能的表面活性剂、有机及无机化合物作增效剂 ,预先或与捕收剂同时处理矿物 ,会获得令人满意的浮选效果 .

Collectors of oxide ores widely applied in industry still take fatty acids, xanthates and their derivatives as dominant factors.Hydroxamic acid is also a kind of su- ccessful collector.The introduction of synergists into collectors can improve their performance.These synergists consist of some reagents with a certain collector function or surfactants,organic and inorganic compounds without any collective performance.When they are used to pretreat the minerals or treat minerals simultaneously with collectors, satisfactory flotation results can be obtained.
