铝土矿是生产氧化铝的主要原料。依铝土矿类型的不同,可用不同的方法选别。浮选是选别细粒嵌布水铝矿最有前途的方法。对单体解离的氧化铝用阴离子正浮选可得到高质量铝土矿精矿,但对于绿泥石化的铝土矿用阳离子反浮选是最有效的。捕收剂用量范围是400～600克/吨,介质pH为8.2～8.4。由于对胺类与铝土矿主要矿物(水铝矿,单水铝矿及鲕绿泥
Bauxite is the main raw material for the production of alumina. Depending on the type of bauxite, different methods can be used for sorting. Flotation is the best way to choose fine grained gibbsite. High-quality bauxite concentrates can be obtained by anion flotation of monomeric dissociated alumina, but are most effective with cationic reverse flotation for chloritized bauxites. Collector dosage range is 400 ~ 600 g / ton, medium pH is 8.2 ~ 8.4. Due to the main minerals of amines and bauxite (gibbsite, monoanalite and oolite
