Abstract In the present study, a comparison of the amenability of a monazite and xenotime (both rare earth phosphates) sample to treatment via alternative extraction techniques was conducted. Monazite and xenotime concentrates were studied under the effects of organic acids and mechanochemical pre-treatment. Maleic, tartaric, citric and oxalic acids have shown the ability to increase the dissolution of phosphorus in the monazite concentrate. Oxalic acid demonstrated to enhance the release of phosphorus (>30%) at pH

磷钇矿和独居石在多个系统中不同反应性的观察

摘要 在本研究中，对独居石和磷钇矿（均为稀土磷酸盐）样品通过替代提取技术进行处理的顺应性进行了比较。在有机酸和机械化学预处理的作用下研究了独居石和磷钇矿浓缩物。马来酸、酒石酸、柠檬酸和草酸已显示出增加独居石浓缩物中磷溶解的能力。已证明草酸在 pH 值下可促进磷的释放 (>30%)
