Q. With reference to Mica, which of the following statements are correct?
Select the correct answer using the code given below.
The correct option is C 1 and 2 only
Explanation:
Statement 1 is correct: Mica is a naturally occurring non-metallic mineral. It is a mineral made up of a series of plates or leaves. It splits easily into thin sheets. These sheets can be so thin that a thousand can be layered into a mica sheet a few centimetres high. Andhra Pradesh, Bihar, Jharkhand and Rajasthan are major producers of mica.
Statement 2 is correct: Due to its excellent dielectric strength, low power loss factor, insulating properties and resistance to high voltage, mica is one of the most indispensable minerals used in electric and electronic industries.
Statement 3 is not correct: Mica is inorganic in origin. Non-metallic minerals are either organic in origin (derived from the decayed animals and plants) such as coal and petroleum or inorganic in origin such as mica, and graphite.
