  • Extraction Development for the Separation of Gadolinium

    2020-7-21 · Xenotime sand a byproduct of the tin mining process of PT Timah is one of the potential gadolinium (Gd) resources. Because of similarities in their physical and chemical properties it is difficult to separate and purify Gd from rare earth elements (REEs) in xenotime sand (i.e. yttrium and dysprosium). In the present work Gd was separated through an extraction process using Cyanex 572.
