DMS and froth flotation are the most widely accepted of all beneficiation techniques across the world. While DMS is suitable for coarsely liberated pegmatites, primarily used as a pre-concentration step, flotation is an efficient unit to recover the finely liberated spodumene not only from the ores but also from the pre-concentrated products.
