Rich Mineral Resources

Mica Mineral

Mica is a mineral name given to a collection of hydrous potassium, aluminum, silicate minerals that are physically and chemically similar. They are all silicate minerals, known as sheet silicates because they form in distinct layers. Among the most important rock-forming minerals, micas are located in all 3 foremost rock types – igneous, sedimentary, and metamorphic.

Micas are fairly light and relatively soft, and the sheets and flakes of mica are flexible. Mica retains its elasticity and toughness even at high temperatures, which is why Mica is best to be used in conditions with extreme humidity and temperatures. The mineral Mica has an absorption range of 2%-5%. Its refractive index is average with a visible spectrum of 1.6. It had the property to withstand and resist all chemicals, alkalis, gasses, oils, and acids.

MiningValleys offers a variety of mica products like natural mica flakes, mica powder, mica sheets in a full range of colors, including white, transparent, black, red-brown, etc.

Great Features


Good Insulation

Mica’s electrical insulation performance is mainfested in four aspects: resistivity, dielectric loss tangent, dielectric constant and dielectric strength.


Good Heat Resistance

When mica is heated by temperature of 100-600, its elasticity and surface properties will not change.


High Strength

If mica’s thickness reaches 0.015mm, its average breakdown voltage would be 2.0-5.7KV, puncture strength would be 133-407KV/mm.


Various Colors

Variety of colours, making mica suitable for different fields, including decoration, electrode, painting material, paint, rubber, fire control, etc.

Application Range

Building Material

Natural mica powder and mica flakes can be used as anew building materials for decorating, painting, and coating.


It can be used as a coating in models of forecasting metal, the brightening material in aluminum, and paint in an electroplating bath.

natural Mica applications

Protective Case

It can be taken as a filler, shelter, lubricating substance, drawing of patterns in plastic, rubber, asbestos products, and sealing materials.

Insulation Materials

It can also be used as a filler in degreasing agent of cosmetics, in insulating materials of high-frequent electric waves and acid-durable products.
