New concepts for lithium minerals processing / Felix Brandt in Minerals engineering, Vol. 23 N° 8 (Juillet 2010) 

Public ISBD [article]  in Minerals engineering > Vol. 23 N° 8 (Juillet 2010) . - pp. 659–661 Titre : New concepts for lithium minerals processing Type de document : texte imprimé Auteurs : Felix Brandt, Auteur ; Reiner Haus, Auteur Année de publication : 2011 Article en page(s) : pp. 659–661 Note générale : Génie Minier Langues : Anglais (eng) Mots-clés : Industrial  minerals  Mineral  processing  Mineral  economics  Liberation  Comminution Résumé : A new concept for the enrichment of lithium minerals is offering higher purity and higher yield by applying new processing technologies addressing the specific properties of the pegmatitic host rock. Additional value is created from high quality by-products which will improve the sustainability of mining activity and the overall cost base. Within the new concept, flotation may even be avoided where wet separation techniques are not applicable. Two innovative processing technologies have been integrated in the new concept: electrodynamic fragmentation and optical sorting. Detailed results of lab-technical tests show that the new process design can achieve highly selective liberation and separation processes. Optical and mineralogical analyses of the test products indicate a high benefit for commercial applications.
