摘要:
利用胶磷矿的粗选试验筛选出SDS和十二醇作为棉油皂脚的增效剂,并将这两种药剂与棉油皂脚复配成低温捕收剂DWB93用于宜昌丁东磷矿正-反浮选闭路试验中,13～15 ℃时,获得了P2O5 30.40%,回收率81.36%的优良指标.表明这种捕收剂使温度对胶磷矿浮选的影响减弱,有利于冬季胶磷矿的浮选.通过表面张力、相对接触角、ξ电位和吸附量研究表明:此种捕收剂能显著地降低矿浆溶液的表面张力,有利于药剂的分散;在T＝13～15 ℃,pH＝10.5的条件下,容易在矿物表面发生化学吸附,有利于磷矿物的浮选.
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.
