Flotation techniques for separation of diaspore from ...

2010-3-1  Starch has a strong depressant effect for diaspore at the alkaline pH region. 2) It is possible to reverse floatation separate diaspore from bauxite ore with 12-4-12 collector and soluble starch at pH 10. The concentrate with Al to Si mass ratio of 9.85 and the recovery of Al 2 O 3 of 70.48% is obtained from low grade bauxite ore (A/S=5.70).

Flotation mechanism of octylic hydroxamic acid on

2013-4-19  Bauxite resources are widely spread in the earth. However, the effective utilization of this mineral is still under infant. The conventional collector for diaspore mineral is oleic acid. It has three main drawbacks which are highly insoluble, large dosages in bauxite flotation, and low selectivity, which hinder its application in industry. In this research, octylic hydroxamic acid was ...

A novel depressor useful for flotation separation of ...

2010-3-1  The essence of reverse floa- tation of bauxite is to sink the diaspore and float the kaolinite, illite, pyrophillite and other silicates [18-19] . Since kaolinite is the main silicate in bauxite the floatation characteristics of diaspore and kaolinite using dodecylamine as the collector were studied.
