离心沉降法去除稀土溶液中杂质铝和铁

Application of Centrifuging Sedimentation on Removing Aluminum and Iron from Rare Earth Solution

将离心沉降技术应用到去除稀土溶液的铁、铝工艺中,重点讨论了溶液pH值、离心时间、转速对铁、铝去除率的影响,得到铁、铝去除率分别大于95%和90%、清澈透明的稀土溶液。

This article applied the centrifuging sedimentation technique into the process of removing aluminum and iron from rare earth solutions. It mainly discussed the effects of the pH value of the solution, centrifuging time,cen-trifuging speed on the removing rate of aluminum and iron. And the authors have got a clear and transparent solution on the removing rate of 95% and 90% for iron and aluminum, respectively.
