Spodumene concentration is a complex process involving dense media separation (DMS), flotation, and magnetic separation. DMS typically processes coarse material (>850 μm) and can produce a coarse final spodumene concentrate while often also acting as an upstream upgrading stage for the flotation feed. This stage serves to …
