细粒云母得到了越来越广泛的应用。用阳离子捕收剂浮选云母是常用的方法之一。因此,研究阳离子捕收剂和云母表面的相互作用机理是非常重要的。许多学者指出,用胺浮选硅酸盐矿物,阳离子捕收剂在带负电的矿物表面上产生物理吸附。云母属于层状结构的硅酸盐矿物,层之间是由水化钾、镁阳离子联接,这些水化阳离子 Fine-grained mica has been more and more widely used. Cationic collector flotation mica is one of the commonly used methods. Therefore, it is very important to study the interaction mechanism between cation collector and mica surface. Many scholars have pointed out that with amine flotation silicate minerals, cationic collectors produce physical adsorption on negatively charged mineral surfaces. Mica belongs to the layered silicate minerals, which are hydrated by potassium hydride and magnesium cations. These hydration cations
