Abstract
SDS and Dodecanol are separated out as synergist from other surfactants by doing experiment on roughing processing. The two synergists and cotton soap are mixed together as a collector DWB9-3 which is used to explore the best technological process of flotation of Ding-dong phosphorite ore at low temperature. The grade of concentrates 30.40％ and the recovery rate of concentrates 81.36％ is gained at 13～15 ℃, this index can meet the demand of industrial manufacture. The conclusion that the effect of temperature affects the flotation is tiny and that this collector can be used in winter is gained from the experiment. Studying on the surface tension, the relative wetting contact angle, adsorption quantity and Zeta-potential, it shows that this collector can depress the surface tension of mash observably and scatter easily in the mash. Chemical adsorption on the phosphorite ore occurs when pH = 10.5 and the temperature is 13～15 ℃, it is good for the flotation of phosphorite ore.关键词
