Is Mica Environmentally Friendly? - Elmelin Ltd

There are two main kinds of mica mining: for sheet mica and for scrap or flake mica. Mining for sheet mica involves either deep shaft or open pit surface mining methods. Once a mica seem is discovered, extracting it involves a careful process. This is because the aim is to maintain the thin, natural sheets of the crystals for later processing.

Mica - Wikipedia

The mica group of sheet silicate (phyllosilicate) minerals includes several closely related materials having nearly perfect basal cleavage.All are monoclinic, with a tendency towards pseudohexagonal crystals, and are similar in chemical composition.The nearly perfect cleavage, which is the most prominent characteristic of mica, is explained by the hexagonal sheet-like arrangement of its atoms.
