    Alexander Poscher, ... Helmut Antrekowitsch, in Rare Earths Industry, 2016. 4 Conclusion. The beneficiation and obtainment of raw materials often has a severe effect on the environment and generates byproducts that in many cases cannot be further processed into suitable products. The high concentration of REs (mainly in the form of oxides) in spent glass polishing material would therefore
