of diaspore and pyrophyllite with the cationic quaternary ammonium DTAL as a collector were studied. The presence of sodium chloride was determined to activate the flotation of pyrophyllite, leaving diaspore flotation unaffected. Zeta potential measurements corresponded to the flotation tests. It is indicated that sodium chloride decreases marked by the zeta potential of pyrophyllite, leaving......
in the Bayer process and clarify the mechanism of how additive lime improves the digestion of diaspore.关键词:......
文献标志码:A Effects of temperature on adsorption amount of sodium oleate on surface of diaspore FENG Qi-ming, XIAO Ya-xiong, LU Yi-ping (School of Minerals Processing and Bioengineering, Central South University, Changsha 410083, China) Abstract: The effects of temperature on the adsorption amount of on the surface of diaspore and its floatation efficiency were revealed......
of the mass ratio. Microscopic observations revealed that, with the size reduction from -1000+710 to -38 μm, the liberation degree of diaspore increased from 10% to 60%, and that of aluminosilicates......
for sulfur removal: 84.21% of S was removed after calcination at 1000°C for 2 min. During the calcination process, diaspore and pyrite were transferred to α-Al2O3, magnetite, and hematite. The phase......
and Bioengineering, Central South University, Changsha 410083, China) Abstract: In single mineral flotation of diaspore, with the oleic acid as collector, the synergistic effect of Tween-20 on the collector.... The experimental results show the potentiator has a marked influence on the recovery of diaspore, which is raised by 12% and the addition sequence also affects the flotation behavior. The reagents should......

. The results show that according to the composition, oolites in bauxite ore-bearing rock system can be divided into aluminous oolite, chlorite oolite, diaspore oolite, hematite oolite and pyrite oolite. The coarse clastic particles in bauxite are the internal clasts formed in the basin, while the argillaceous coarse clastic particles do not reflect the high energy environment. The diaspore......
