Mica deposits are either mined for mica only, when matrix yield is high enough, or in association with other minerals such as kaolin/feldspar. 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.
