摘要
本文报道用沉淀浮选法提取稀土元素。对表面活性剂的选择,溶液酸度,离子强度和共存离子等对稀土元素浮选回收率的影响进行了系统研究,结果表明阴离子表面活性剂硬脂酸钠的浮选效果较好,稀土浮选回收率在96%以上。
Reported here is the precipitate flotation of rare earth elements. The effects of different kinds of surfactants, acidity, ionic strength of solution and coexisting ions on recoveries of rare earth elements have been studied. Sodium stearate,an anionic surfactant, was found to be the best surfactant for the precipitate flotation of rare earth elements and the recovery of rare earth elements is more than 96%.
