从稀土矿石浸出液中分离稀土元素——2.用P507解吸树脂上的稀土制备钇富集物

SEPARATION OF RARE EARTHS FROM ORE LEACHING LIQUOR(II) PREPARATION OF YTTRIUM CONCENTRATE USING DESORPTION OF RARE EARTHS FROM RESIN BY P507

本文报道在连续逆流离子交换塔中用P507从阳离子交换树脂上解吸稀土的小型试验和扩大试验结果。采用这项技术可以从矿石浸出液制备钇富集物。

This paper presents the results of the laboratory test and the pilot plant test in which the rare earths were desorbed from the cation-exchange resin by P507 using continuous counter-current ion-exchange device. The mentioned technology can be used for producing yttrium concentrate from ore leaching liquor.
