摘要
通过对微细粒菱铁矿的疏水絮凝试验研究、ＳＥＭ扫描电镜拍摄、接触角θ及矿粒表面油酸钠吸附面密度σ的测定和计算，提出了关于表面活性剂在菱铁矿表面吸附与疏水絮凝。
On the basis of the experimental research on the hydrophobic flocculation of fine siderite ore,the shooting with scanning electron microscope and the measurement and calculation of the contact angle θ and the adsorption layer density σ of sodium oleate on the surface of ore particles,the paper puts forward the mechanism of the surfactant adsorption on siderite surface and hydrophobic flocculatoin and neutral oil intensified hydrophobic flocculation.
