焦性没食子酸对硫化矿物的抑制性能和作用机理

Research on the effects of pyrogallic acid on flotation behavior of sulphide minerals and its interaction mechanism

研究了焦性没食子酸对硫化矿物浮选行为的影响及其作用机理 ,结果表明焦性没食子酸对方铅矿、黄铁矿、黄铜矿、闪锌矿具有抑制作用 ,对毒砂没有抑制作用 .通过量子化学计算、亲固能计算以及能带结构分析等方法探讨了焦性没食子酸对硫化矿物的抑制机理 .

the effect of pyrogallic acid on flotation behavior of sulphide minerals and its interaction mechanism have been studied in this paper. Results show that galena, pyrite, chalcopyrite, sphalerite will be depressed in the presence of pyrogallic acid but arsenopyrite will not. The mechanism of pyrogallic acid depressing sulphide minerals has been discussed by means of HMO calculation, interaction energy and energy band structure.
