La mine de phlogopite du lac Letondal est le seul gisement de mica exploité actuellement au Québec et au Canada. La mine est située à 11 km au nord du lac Letondal (région de Parent), au nord de la Mauricie. Le gisement est une intrusion de roches à très haute teneur en phlogopite connue sous le nom de « mica .

Feb 15, 2014· USA Mica production in this country chiefly comes from Spruce Pine, Franklin Sylva and Shelby Hickory districts of North Carolina. Production is mostly that of scrap mica. It is obtained during the mining of felspar and quartz. For blocks, splittings and condenser films, the USA depends solely upon India and Brazil. 12.

The principal mica minerals used in commercial applications are biotite, muscovite and phlogopite. Biotite is generally used in its ground (particulate) form as a soil additive; muscovite and phlogopite have applications in sheet and ground forms.

The mica group represents 37 phyllosilicate minerals that have a layered or platy texture. The commercially important micas are muscovite and phlogopite. Layering in the univalent (potassium, sodium), or true, micas imparts perfect basal cleavage, allowing crystals to be split into very thin sheets that are tough and flexible.

Madagascar Mining. Madagascar was the tenthlargest producer of chromite (chemical and metallurgicalgrade), and its mining industry has also been known for the production and export of phlogopite mica and highquality crystalline flake graphite. Chromite and petroleum products were top export commodities...

Mica mining, because of the necessity of keeping the crystals intact, is a delicate operation; drills and blasting powder must be used carefully, if at all. The mined crystals are first cobbed,, roughly trimmed of rock and cut, then split with a hammer into plates, and further split into sheets with a knife.

Muscovite is the most common mineral of the mica family. It is an important rockforming mineral present in igneous, metamorphic, and sedimentary rocks. Like other micas it readily cleaves into thin transparent sheets. Muscovite sheets have a pearly to vitreous luster on their surface.

Mica is a generic name for a group of silicate minerals which, have chemical as well as physical traits. They are also referred to as sheet silicates since they occur in layers, each layer separate and distinct from the other. Mica is a considerably light mineral which is comparatively soft and flexible when it occurs in sheets or as flakes.
