Mica Mineral Lumps

Mica is one of the wonderful bounty of nature which occurs in pegmatite usually in book form & can be cleaved up to 0.25 millimeters in thickness. Mica is chemically silicate of aluminium with some water of crystallization containing one or more elements like potassium, sodium, magnesium, lithium, vanadium, & iron. Of all the species known muscovite & paragonite are of commercial importance. It is available as both dry ground Mica and wet ground Mica. Mica is a natural valuable mineral product applied to a group of a complex terminological minerals having a sheet or plate like structure with different chemical compositions and physical properties. All micas form flat six sided monoclinical crystals with a remarkable cleavage in the direction of the large surfaces, which permits them to split easily into optically flat films, as thin as one micron in thickness. When split into thin films, they remain tough and elastic even at high temperature
