Spodumene ores are typically consolidated from ore comprising 1–1.5% Li20 to a concentrate of about 6–6.5% Li20. To achieve this, the ore passes through a typical concentrator-type plant, flowing from crushing and grinding, to gravity separation and DMS, to flotation, and then to the final
Le spodumène est un minéral relativement nouveau pour la science, découvert au cours des trois derniers siècles et les variétés de pierres précieuses n'ont été découvertes qu'au cours des 120 dernières années. Le spodumène est présent en blanc, gris, rose, lilas et vert. Il a un lustre vitreux et un indice de dureté de 6,5 à 7,5.
