摘要
研究了捕收剂季铵盐Y28对一水硬铝石与脉石硅酸盐矿物高岭石和白云母的浮选行为,通过吸附量、接触角、Zeta电位、FTIR分析和XPS分析对Y28与矿物表面的作用机理进行了探究。结果表明:捕收剂Y28用量90 mg/L、矿浆pH值为7时,一水硬铝石回收率为25.63%,高岭石和白云母回收率分别为83.21%和81.24%;Y28主要以物理吸附的方式吸附在矿物表面,吸附强度顺序为:高岭石>白云母>一水硬铝石。
Experiments were performed to study the effect of quaternary ammonium salt Y28,as a collector,on the flotation performance of diaspore and gangue silicate minerals of kaolinite and muscovite,and the interaction mechanism between Y28 and the surface of minerals was also explored by analyzing adsorption capacity,contact angle,zeta potential,FTIR analysis and XPS analysis.The results show that with the collector Y28 at a dosage of 90 mg/L and pulp pH of 7,the recoveries of diaspore,kaolinite and muscovite were 25.63%,83.21%and 81.24%,respectively.The collector Y28 is primarily adsorbed onto the surface of the minerals by physical adsorption,with the adsorption strength in the following descending order:kaolinite>muscovite>diaspore.
