摘要
本文通过实验研究了水杨醛肟对氧化锌矿物(菱锌矿和异极矿)浮选的活化效应,研究结果表明,菱锌矿和异极矿经水杨醛肟活化后可不经硫化,直接用黄药有效地加以浮选这种水杨醛肟活化——黄药法较之通常的硫化——黄药法或硫化—胺法具有药剂耗量低,回收率高和浮选选择性好等优点.
The activating effect of salicylaldoxime on oxygen Zinc minerals(Smithonite and hemimorphite )flotation was saudied thrangh experiments.The results showed that smithonite and hemimorphite after being activated by salicylaldoxime,can be floated effectively by xanthate without sulfidzing,Compared with the common sulfidizing—xanthate method or sulfidizing—amine method,this salicylaldoxime acti- vating—xanthate method,has the advantages of lower reagent consumption,higer recovery and bether flotation selectivity.
