摘要
目前菱锌矿常用的浮选方法有硫化-浮选法和直接浮选法。但由于菱锌矿具有嵌布粒度细、矿石结构复杂且泥化严重等特点,导致上述浮选工艺存在药剂消耗量大、选别难度大、精矿品位、回收率和富集比都偏低等问题。为了解决这些问题,选矿工作者进行了大量的浮选药剂作用机理研究。对此,本文以硫化-浮选法、直接浮选法和其他捕收剂浮选法为切入点,对硫化-黄药浮选法中的加温强化硫化、药剂强化硫化以及活化作用;硫化-胺类浮选法中的药剂抑制作用、混合药剂强化捕收作用;脂肪酸直接浮选以及螯合剂直接浮选等浮选工艺过程中所用药剂的作用机理进行了综述。
At present,the common flotation methods of smithsonite are sulfide-flotation,direct flotation and other collector flotation methods.However,smithsonite has the characteristics of fine disseminated particle size,complex structure and serious sliming,which leads to some problems in the above flotation processes.In order to solve these problems,beneficiation workers have done a lot of research on the mechanism of flotation reagents.Therefore,this paper takes sulfide-flotation method,direct flotation method and other collector flotation methods as the starting point.Heating-enhanced vulcanization,reagent-enhanced vulcanization and activation in vulcanization-xanthate flotation method;Inhibiting effect of reagents and strengthening collecting effect of mixed reagents in sulfide-amine flotation method;Direct flotation of fatty acids;The action mechanism of reagents used in flotation processes such as chelating agent direct flotation method and new collector direct flotation method is reviewed.
