In this paper,based on comprehensive information,combined with that bauxite is commouly characterized by diaspore,higher Al and Si,lower Fe, the Series-combination with Ore Mixing technology is put forward as the alumina production process.

本文在综合资料的基础上，结合我国铝土矿多为一水型硬铝石，具有高铝、高硅、低铁的特点，提出配矿串联法生产氧化铝工艺。

The results indicate that SA3、1230 and 1231 have a depression effect on diaspore,while 1230 and 1231 also have a depression effect on aluminosilicate minerals ,even on illite.

In this paper, the synthesis of alkyl-guanidine sulfate s and its flotation properties to diaspore, kaolinite, pyrophyllite and illite have been started.

本文系统地研究了烷基胍硫酸盐系列捕收剂的合成方法及其对一水硬铝石、高岭石、叶蜡石和伊利石的浮选性能，通过矿物的接触角测量、ζ-电位测定和红外光谱分析等手段，探讨了烷基胍类捕收剂与铝硅矿物的作用机理。

The results show that the chief mineral is diaspore(size of 5 ~20 nm) and the iron minerals are hematite and limonite mainly, whose sizes are 0.5~3.0 mm.

研究结果表明： 2个样品中的铝矿物为晶体粒度细小的一水硬铝石(粒度为5~20 nm)；铁矿物主要为赤铁矿和褐铁矿，铁矿物嵌布粒度相对较粗(粒度为0.5~3.0 mm)。

Results of flotation show that the diaspore can be strongly depressed when BK501A is put into pulp,but it almost has not any effect on the flotability of kaolinite.

浮选试验表明，通过加大药量，一水硬铝石在广泛的pH范围内被抑制，而对高岭石的可浮性影响很小。

Influences of phosphates on the dispersion of diaspore, kaolinite, illite and pyrophyllite were systematically investigated by sedimentation experiments.

摘 要：采用沉降实验考查磷酸盐对一水硬铝石、高岭石、伊利石和叶蜡石分散行为的影响规律。
