摘要
通过红外光谱等手段研究苯甲羟肟酸与铌钽锰矿作用机理,认为苯甲羟肟酸对铌钽锰矿的捕收作用,主要在铌钽锰矿表面生成五元环螯合物,以化学吸附为主。根据铌钽锰矿晶体结构分析认为,Mn2+是铌钽锰矿的主要浮选活性中心。
This paper introduced the action mechanism between benzylhydroxmic acid and columbite-tantalite by IR spectrophotometer. The test results indicating： Mn^2＋ of the columbite-tantalite surface chelated with benzylhydroxmic acid to form five ring chelate matter, chemistry adsorption is the most important action. According to the crystal structure characteristic of columbite-tantalite,Mn^2＋ is thought as primary flotation active center.
