Sheet mica is used principally in the electronic and electrical industries. Its usefulness in these applications is derived from its unique electrical and thermal properties and its mechanical properties, which allow it to be cut, punched, stamped, and machined to close tolerances.
What industry uses the most mica?
Only about 18 percent of mined mica goes into cosmetics. The electronics industry is the biggest user, with about 26 percent, followed closely by the paints, pigments and ink sector, at 24 percent. But cosmetics, to date, has been the sector most under scrutiny for its mica sourcing practices.
Why is mica used in electronic industries?
Mica is one of the most indispensable minerals used in electric and electronic industries, due to its Di-electric strength, low power factor, insulating properties and resistance to high voltage.
Where is mica used in electrical appliances?
Mica sheets are used to provide structure for heating wire (such as in Kanthal or Nichrome) in heating elements and can withstand up to 900 °C (1,650 °F).
Which country has largest mica?
The largest mica producer in the world in 2020 was China, producing about 95,000 metric tons of mica. Following China was Finland, which produced 65,000 metric tons that year.

Why is mica shiny?
Mica minerals! … They sparkle because light is reflected on their flat surfaces, which are where the mineral breaks along its plane of cleavage. These minerals break so easily along their cleavage that some crystals have broken into many thin layers that look like the pages of a little book.
Why should minerals be conserved?
Conservation of mineral resources is essential because they are a country’s valuable possession. … Minerals should be used in a planned and sustainable manner. Technology should be upgraded to allow the use of low-grade ore at low costs. Recycling of metals also results in the conservation of mineral resources.
