摘要

单矿物试验表明,以化工废料为原料合成的新型捕收剂D16-4对白钨矿的选择性、捕收能力强于传统药剂氧化石蜡皂(731).表面动电位测定和红外光谱分析表明,在pH=11.0的强碱性矿浆中,水玻璃和捕收剂D16-4均以化学作用吸附在白钨矿、萤石和方解石表面;在大量水玻璃的作用下,D16-4在白钨矿表面仍有强烈的化学吸附,而在方解石和萤石表面的吸附减弱.与常规药剂731相比,用D16-4可更有效地实现白钨矿与方解石、萤石的浮选分离.
        The single mineral test shows that the new collector D16-4 synthesized by chemical waste has a higher selective collective ability to scheelite than traditional oxidized paraffin soap(731).The surface potentiodynamic measurement and infrared spectroscopy analysis show that the water glass and the collector D16-4 are all chemically adsorbed on the surface of scheelite,fluorite and calcite in strong alkali ore pulp with pH=11.0.Under the effect of a large amount of water glass,there is still a strong chemical adsorption on the surface of the scheelite,while the surface adsorption of calcite and fluorite is weakened.Compared with the conventional agent 731,the new collector synthesized effectively realizes the flotation separation of scheelite from calcite and fluorite.
