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.

In general, iron ore beneficiation is done at the mining site. The concentrated iron ore is subsequently sintered or pelletized, depending on the grain size distribution, before it is charged to an ironmaking plant. In cases where after the initial processing steps the iron ore fractions are of inferior quality (too fine or low iron content ...
