Mica is not considered rare as it is widely distributed around the world. It is commonly found in igneous and metamorphic rocks, and is used in various industries such as electronics, construction, and cosmetics. However, certain varieties of mica with specific characteristics or from particular locations may be more valuable or sought after.

No, mica does not taste salty. Mica is a mineral commonly used in cosmetics, pigments, and electronics, but it is not intended for consumption. Eating mica can be harmful to your health.
Another name for mica is isinglass.
Mica can range from pale grey to black.
Muscovite (clear) and Biotite (black) are the commonest mica forms. Fuchsite (green) is an unusual mica containing chromium. Please see the related link below for a listing of the mica group of minerals.

Biotite mica contains iron and/or magnesium, but muscovite mica does not.
Iron is present in biotite mica but not in muscovite mica.

No. Mica is a silicate.
Mica itself is a mineral resource, and minerals are generally considered non-renewable as they are finite and cannot be replaced on a human timescale. The extraction of mica can also have negative environmental impacts if not managed sustainably.
Mica Gallery was created in 1992.
The various types of mica do not contain elements which are significantly radioactive, e.g. K, Al, Si, O, F, H, Mg. (Rare isotopes of several common elements are part of the normal background radiation and no excess of these is found in mica.) Of course, there is the possibility that at any given mining site there can be contamination from other sources, but that is true of anything. Some examples showing the elements in mica are given below. The mica group contains 37 different sheet silicate (phyllosilicate) minerals. The chemical formula for the various types is complicated. Here are two common examples. Common mica (also called Muscovite ) is KAl2(AlSi3O10)(F,OH)2, or (KF)2(Al2O3)3(SiO2)6(H2O). Magnesium mica (Phlogopite) has the chemical formula KMg3AlSi3O10(F,OH)2. There are many more forms in the mica group of 37 phyllosilicate minerals.
Another name for the mineral muscovite is white mica.
Mica is nonmetallic.
