In the mica open pit mine, the ore body is shallowly buried and the veins are small and scattered. In order to protect the mica crystals, when you start open pit mining, youd better not use rake equipment in the stope face. The mining method should be kept as simple as possible. Most of the deposits use open pit mining, whose industrial raw material mica reserves less than 200t. At present, there is no clear standard for the division of the mining scale of mica ore deposits. Generally, the annual mining volume of large scale mica mine is 60,000 to 100,000 tons, and the service life is between 10 to 6 years. The annual output of industrial raw material mica in large mines is 90 200t/a.

Mica underground mining, like other minerals, mainly is digging a series of tunnels underneath which are leading directly to the ore body. In practice, the widely used mica underground mining methods are horizontal layered filling mining and ore retention, stage forced caving and stage mine combined mining.

Mica Minerals Education Coalition

Mica is a mineral name given to a group of minerals that are physically and chemically similar. They are all silicate minerals, known as sheet silicates because they form in distinct layers. Micas are fairly light and relatively soft, and the sheets and flakes of mica are flexible. Mica is heat resistant and does not conduct electricity. There are 37 different mica minerals. The most common include: purple lepidolite, black biotite, brown phlogopite and clear muscovite.

IMAR 7thEdition The mica industry can be divided into two distinct but interdependent industries: those that produce sheet mica, and those that produce flake mica. Each industry, although somewhat dependent on the other, produces different end products. Sheet Mica Mining: Sheet mica is recovered by either sinking a shaft along the strike and dip of a pegmatite or by open pit surface mining of semi hard pegmatite ore. In either case, it is a very economically risky mining procedure because of the cost involved in locating the vein and the unpredictability of the quality and quantity of the mica that might be recovered once the vein is located and worked. In underground mining, the main shaft is driven through the pegmatite at suitable angles to the dip and strike using air drills, hoists and explosives. Crosscuts and raises are developed to follow promising exposures of mica. When a pocket of mica is found, extreme care is exercised in the removal to minimize damage to the crystals....

The principal use of ground mica is in gypsum wallboard joint compound, where it acts as a filler and extender, provides a smoother consistency, improves workability, and prevents cracking. In the paint industry, ground mica is used as a pigment extender that also facilitates suspension due to its light weight and platy morphology. The ground mica also reduces checking and chalking, prevents shrinkage and shearing of the paint film, provides increased resistance to water penetration and weathering, and brightens the tone of colored pigments. Ground mica also is used in the well drilling industry as an additive to drilling muds. The plastic industry used ground mica as an extender and filler and also as a reinforcing agent. The rubber industry uses ground mica as an inert filler and as a mold lubricant in the manufacture of molded rubber products, including tires. Sheet mica is used principally in the electronic and electrical industries. The major uses of sheet and block mica are...
