2010-3-22 Diasporic-bauxite ore used in the bench-scale flotation tests was obtained from Henan Province, China. This sample with Al2O3 head assay of 64.55% and SiO2 head assay of 11.32% was mainly composed of 67.56% diaspore, 10.8% kaolinite, 6.9% illite, 3.1% pyrophyllite and 0.7% chlorite by the X-ray diffraction analysis and
Bench scale flotation tests for diasporic bauxite ore and micro-flotation tests for relevant pure minerals (including diaspore, pyrophyllite and kaolinite) were carried out at different conditions
2020-11-10 Theoretically, approaches for the flotation desilication of diasporic bauxite can be divided into direct flotation (flotation of diaspore and depression of aluminosilicates) and the reverse...
2014-10-1 According to zeta potential measurement, minerals diaspore, kaolinite, illite and pyrophyllite, operating PZC diaspore, kaolinite, illite and pyrophyllite, were respectively about 6.68, 3.65, 2.88 and 2.51 It was suggested to conduct the separation by using diaspore floatation method of kaolinite, illite and pyrophyllite, with a cationic
