Spodumene concentration Spodumene ores are typically consolidated from ore comprising % Li20 to a concentrate of about % Li20. To achieve this, the ore passes through a typical concentratortype plant, flowing from crushing and grinding, to gravity separation and DMS, to flotation, and then to the final dewatering of the concentrate.

Five grams of αspodumene (74149 µm) were mixed with different amounts of KF ( g per gram of spodumene) for 5 min in a mortar. The reagent mixtures were placed in ceramic crucibles and placed in a muffle. Then, the mixtures were calcined isothermally for different temperatures (500800 °C) and periods (5180 min).

Working principle When the natural spodumene is about 1100 °C, its crystals change from α type to β type, and at the same time, the volume expands and easily breaks into powder. Through grinding and screening producers, can achieve separation of spodumene and gangue minerals. (4) Heavy medium separation (HMS / DMS)
