The mica group of sheet silicate [phyllosilicate] minerals includes severals closely related material having highly perfect basal cleavage. All are monoclinic with a tendency towards pseudohexagonal crystal and are similar in chemical.

Compsition. The highly perfect cleavage, which is the most prominent characteristic of mica is explain by the hexagonal sheet like arrangement of its atoms. The words "mica"is drived from the Latin word mica meaning "a Crumb"and probably influenced by micare, "to glitter.

The mica group of sheet silicate (phyllosilicate) minerals includes several closely related materials having highly perfect basal cleavage. Latin world-mica, means-a crumb probably influenced by micare, "to glitter".

Mica is a shiny silicate mineral with a layered structure, found as minute scales in granite and other rocks, or as crystals. It is used as a thermal or electrical insulator.

Mica is a good conductor of heat, but a bad conductor of electricity. So it is used in Irons (the device used to press clothes).

China was the top producer of Mica with almost a third of the global share, closely followed by the US, South Korea and Canada.

Is they mica is correct ans? In India most of the people are invest in gold only how is mica?
Please clear my doubts.

Mica is several closely related materials having highly perfect basal cleavage, Mica is our india's largest ore.

Gold is largely produced by South Africa while copper produced largely in chile and second country is China.

Ore :The compound of metals which is directly obtain from the nature with other impurities is called ore.

Please tell me about the copper and gold & which has the largest production of copper and gold.
