Abstract (en)
[origin: WO2012143240A2] The invention relates to a novel method comprising the step of separating rare earths. The separation is carried out in at least one separating step by means of at least one of the following methods: use of columns; use of mixer-settlers; use of ion chromatography. Said method can be used to especially produce stabilised illuminants and to economically produce light sources.
