Processed Mica

The crystals of mica extracted from the mines are in the form of rough lumps of irregular shape, size and thickness associated with impurities and structural imperfections. They have to undergo a lengthy operation of cutting, cleaning, sorting and processing from crude to commercial quality which involves skilled labour and intensive technique.

Mica Blocks

Mica Blocks

Knife or scissor dressed sheet mica with irregular shape and a minimum thickness of 0.18 mm (0.007 inch or 7 mils) are called Mica Blocks. Block Mica are classified into thirteen size groups (ranging from OOEE Special down to No. 7) and obtained in size as large as 30 – 35 cm sq. (12 – 14 inches sq.) beyond which is practically rare and far too expensive. It is available in sheets with both random (natural) and calibrated thickness as per demand. After undergoing size and quality grading, Mica Blocks are exported.

Mica Thins

Mica Thins

Knife or scissor dressed sheet mica with irregular shape having a specified thickness range between 0.05 to 0.18 mm (0.002~0.007 inch or 2~7 mils) are classified as Mica Thins. It is used to manufacture various kinds of fabricated mica.

Mica Flims

After undergoing size and quality grading, Mica Blocks are exported.

Mica Scrap

Mica Scrap

Mica recovered by means of hammer crushing, processing and screening of crude mica having an average area between 12 to 50 mm sq. (1/2 to 2 inch sq.) is defined as Mica Scrap. All Mica Scrap are substantially free from mineral and non-mineral impurities as well as other foreign inclusions. It is exported to plants all over the world and finds paramount use as a primary raw material in the manufacture of mica paper or re-constituted mica. Domestically, Mica Scrap is used as a basic material for the manufacture of Ground Mica Flakes and Powders. It is also widely used to make mica paper.

Mica Splittings

Mica Splittings

Laminae split from mica blocks and mica thins where the combined thickness of ten sheets taken together does not exceed 0.30 mm (0.012 inch or 12 mils) are classified as Mica Splittings. Splitting Mica is chiefly used in the manufacture of micanite or built-up mica products for ultimate use as an insulating material. It is available in “Loose Form” and “Book Form” types.
