RE:YAG Recovery method rare earth elements from waste RE:YAG crystal

机译:RE:YAG从废RE:YAG晶体中回收稀土元素的方法

摘要

The present invention separates the rare earth component and aluminum from the waste RE: YAG single crystal, that is, a single rod left after processing into a rod and square shape for laser and a RE: YAG residual melt (ie, a melt left in the crucible after single crystal growth). And a method for recovering, and more specifically, heating and dissolving the waste RE: YAG crystal using a mixed acid solution to prepare a waste RE: YAG solution, and then precipitating and recovering the prepared solution and treating it with a basic compound and leaching with acid The method comprises the steps of separating the rare earth component and the aluminum, thereby recovering the rare earth component from the waste RE: YAG crystal.
