. A complex alkali resistant phosphate surfactant with good permeability was prepared. The wettability of surfactants was investigated by measuring the immersion time, sinking time and capillary effects..., the complex system exhibits better wettability in 5.0-7.0 mol/L of NaOH solutions, in comparison with either corresponding single surfactant component employed, and wettability is well correlative......
in promoting nickel nucleation than 500 nm particles due to an increase in active nucleation sites. In terms of surfactants, anionic surfactant sodium dodecyl sulfate (SDS) produced better dispersion of 40 nm silicon carbide particles than cationic surfactant cetyltrimethyl ammonium bromide (CTAB), but little difference was found between the two when 500 nm silicon carbide particles were used......
that the mixed surfactant of Tween80 and sodium oleate with mass ratio of 1?9 is helpful for the flotation of diaspore, but further increasing Tween80 is not benefit for the flotation by mixed surfactant...; mixed surfactant 自2003年中国铝业中州分公司建成投产了铝土矿选矿脱硅--拜耳法生产氧化铝新工艺以来,选冶联合可以经济地利用占我国铝土矿资源80%以上的 中低品位矿石[1].因此,铝土矿选矿脱硅也得到了 越来越多的重视和应用,同时也需要进一步认识和 优化. 目前,在工业应用的铝土矿选矿脱硅技术是正浮选脱硅.铝土矿正浮选脱硅[2]过程的实质......
