Mica | IMA Europe
When Mica is present in soft rock, it is beneficiated through wet processing, typically blunging, gravity separation and flotation. Mica is subsequently dried to attain a moisture content below 1%. In hard rocks, the preferred process is crushing, directly after drying, followed by sieving and magnetic separation.
