Mica is a group of thirty seven minerals that are physically and chemically similar. They are all sheet
silicate minerals (form in distinct layers). Micas are lightweight and soft, and the sheets and flakes of
mica are flexible. Mica has a pearly or vitreous luster and is heat-resistant and does not conduct
electricity. There are four minerals that are most commonly associated with the word Mica:
Lepidolite (purple, pinkish, silver or gray)
MicaBiotite (dark green, brown or black)
MicaPhlogopite (brown, yellowish-brown or green- white)
MicaMuscovite (colorless or transparent) Mica
There are basically two types of mica that are found in North Carolina. They are Sheet Mica and Flake
Mica. North Carolina produces about half of all Mica mined in the USA. Scrap Mica is mica that because
of size, color, or quality is below the standards for being called sheet mica. The term Scrap Mica
includes flake mica, mica (except sheet) obtained from pegmatite mining or waste from the preparation
and fabrication of sheet mica.
Mining Sheet Mica is extremely cost prohibitive since it is difficult to locate and is generally found in a
hard pegmatite ore. The removal of the delicate mica from this ore requires precision blasting and very
cautious handling during extraction.  Sheet mica is no longer mined in the United States due to the high
cost of mining and a low demand for Sheet Mica. Currently most sheet mica is mined in countries where
labor costs are low enough to make it a profitable venture.
Mining Flake Mica is a more practical venture. It is generally found in schist or pegmatites and is mined
by conventional open-pit methods. In soft materials, bulldozers, track hoes and front end loaders are
used in the mining process. Hard-rock mining of mica-bearing ore (such as found in quartz) requires
drilling and blasting. After blasting the rough ore is sent to a processing plant, where mica is extracted
from the ore and associated quartz and feldspars are removed.
The section of the mountains in Western North Carolina where we found this mica is in the Clear River
Valley near Lake Toxaway in Transylvania County. The mica found here is normally formed in layers of
schist like Mica mixed with layers of quartz and Albite. We have obtained exclusive access to this area.
Excavation has been done with a skid steer and a tractor front loader. Specimens are then pulled out by
hand and cleaned.
The primary uses of ground flake or scrap mica are in gypsum wallboard joint compound, paint, plastics
and rubber industries. Mica is used as filler or an extender.  Sheet mica is used principally in the
electrical, heating stoves or kerosene heating industries. It is an electrical and thermal insulator.
