铝硅酸盐矿物是层状硅酸盐矿物,破碎后晶体端面荷电是表面原子的选择性吸附和解离而成,并随pH变化而变化,其层面荷电为金属离子的晶格取代造成,荷永久负电荷,不随溶液pH值变化而改变.阳离子捕收剂是铝硅酸盐矿物捕收剂的设计首选.多胺类药剂与十二胺相比增加了吸附活性点,浮选性能得到改善.有关参数的计算结果说明多胺类药剂是比十二胺更佳的铝硅酸盐矿物捕收剂.浮选试验也证实这一结论.
The aluminosilicate minerals are layered silicate minerals. After the crushing, the end faces of the crystals are charged by the selective adsorption and dissociation of the surface atoms, and change with the change of the pH. The charge of the layers is caused by the lattice substitution of the metal ions , Permanent long negative charge, does not change with the pH value of the solution.Cationic collector is the first choice for the design of aluminosilicate mineral collectors.Polyamines and dodecylamine increased the adsorption active point, the flotation performance The results of the calculation of the parameters show that polyamines are better aluminosilicate minerals than dodecylamine flotation tests confirm this conclusion.
