explored and produced many types of high-quality silica sand used for glass making, ceramic, foundry, sport yard and Water filtration.

Limestone is a sedimentary rock composed largely of the minerals calcite and aragonite, which are different crystal forms of calcium carbonate (CaCO3).
we can reach up to 45 micron.
Uses limestone:
1- Portland cement industry: about 76 % that mix with nonmetallic minerals which is chemically treated.
2- Anhydrous sod carbonates: which is important to glass industry, detergence industry, purification industry, by reaction of co2 produce from calcinations with sod chloride and ammonia.
3- Catalyst in iron kilns: that iron have silica and ammonia as impurities which removed by limestone, they found that 410 kg of limestone produce 1 ton of iron.
4- Rocky fiber: by melting limestone in kilns and pumping steam strongly, so fiber formed which use as thermal isolation.
5- Lime industry: limestone is fired to lose co2 with 44 % from its weight leaving cao, that happen at 1000 – 1100 degree, which use in glass, paper building industry.
6- Metal filler: easy to grind, low oil absorption, do not cause machine corrosion isolation of tank and roofs,, painting and ceramic industries.
7- Food industry: the pure one for birds, treatment for sugar.
8- Ornamental stone: and building.
9- paper: In alkaline papermaking, calcium carbonate is used as a paper filler and coating. Both uses require high brightness, high purity, small particle size, and lack of abrasion.
10- coating: used white pigment in paints because it is available at relatively low cost and has high brightness for TiO2 extension, high purity, low abrasivity, and resistance to weathering.
11- plastic and rubber industry: used filler in plastics due to its low cost, low abrasion, low oil absorption, low moisture, high brightness, and easy dispersion with conventional mixing equipment, In plastics they are used to improve mar and impact resistance, surface gloss, weatherability, shrin

Uses of feldspar
Feldspar use in several industries like
1-,glass industry : by percent 10-15% from the formula that chemical balance happen due to presence of aluminum and basis contain 4-6% K2O, 5-7% Na2O, about 19% Al2O3, and less than 0.1% Fe2O3. Feldspar is used mainly as a source of alumina, which improves both the workability of the glass melt and the chemical and physical stability of the finished product. It also provides the alkaline oxides (Na2O, K2O) that provide fluxing in partial substitution for calcium oxide, which improves chemical resistance,
2-, ceramic , porcelain and pottery : as flux to accelerate the melting operation that feldspar melt in lower temperature than the other materials in the formula so can enter to the chemical and physical reaction during melting .
3-,other uses : as scraping off material ,
4-,filler material in plastic ,
5-,rubber ,
6-,painting industry .
7-,know as electric isolator ,
8-, dental ,
9-, a flux in welding electrodes,
10-,adhesives,
11-, coatings.
12-,In filler applications it offers low vehicle demand, high dry brightness with low tint strength, and resistance to abrasion and chemical degradation. In coatings it also provides good film durability and high resistance to chalking and frosting.
13-,Some intergrowths of orthoclase and albite have an attractive pale lustre and are called moonstone when used in jewellery. Most moonstones are translucent and white, although grey and peach-colored varieties also occur. In gemology,
14-,The gemstone commonly called rainbow moonstone is more properly a colourless form of labradorite and can be distinguished from "true" moonstone by its greater transparency and play of colour, although their value and durability do not greatly differ.

Feldspar minerals potassium, aluminosilicates. Their ores are commonly associated with quartz.
we have Nak feldspar, k feldspar 1st and 2nd grade.
we can reach up to 45 micron milled feldspar with magnetic separation.

TALC ROCK
Talc has the ability to absorb moisture, oils, odor, serve as a lubricant, and produce an astringent effect on human skin. These properties have made talcum powder an important ingredient in many baby powders, foot powders, first aid powders, and a variety of cosmetics.
Uses of Talc
1 Plastics
It is mainly used as a filler. Increase the stiffness of products such as polypropylene, vinyl, polyethylene, nylon, and polyester .It can also increase the heat resistance of these products and reduce shrinkage.
2 Ceramics
In the manufacturing of ceramics products such as bathroom fixtures, ceramic tile, pottery, and dinnerware. Improve the firing characteristics of the green ware and the strength of the finished product.
3 Paint
Talc is used as an extender and filler in paints. The platy shape of talc particles improves the suspension of solids in the can and helps the liquid paint adhere to a wall without sagging.
Talc an excellent filler in paint because it simultaneously serves to whiten and brighten the paint.
4 Paper
Talc as a mineral filler can improve the opacity, brightness, and whiteness of the paper. Talc also can also improve the paper�¯�¿�½?�?�¢??s ability to absorb ink.
5 Cosmetics and Antiperspirants
Talc is used as the powder base of many cosmetic products. The tiny platelets of a talc powder readily adhere to the skin but can be washed off easily.
Talc�¯�¿�½?�?�¢??s softness allows it to be applied and removed without causing skin abrasion.
The ability of talc to absorb moisture, absorb odor, adhere to the skin, serve as a lubricant, and produce an astringent effect in contact with human skin make it an important ingredient in many antiperspirants..
6 Roofing Materials
Talc is added to the asphaltic materials used to make roofing materials to improve their weather resistance. It is also dusted onto the surface of roll roofing and shingles to prevent sticking.
7 Dimension Stone
A rock is known as �¯�¿�½?�?�¢??soapstone�¯�¿�½?�?�¢?? is a massive variety of talc with varying amounts of other minerals such as micas, chlorite, amphiboles, and pyroxenes.
It is a soft rock that is easy to work, and that has caused it to be used in a wide variety of dimension stone and sculpture applications.
8 It is used for countertops, electrical panels, hearthstones, figurines, statuary, and many other projects.
9 Ground talc is used as a lubricant in applications where high temperatures are involved.
10 It is able to survive at temperatures where oil-based lubricants would be destroyed.
11 Talc powder is used as a carrier for insecticides and fungicides.
12 It can easily be blown through a nozzle and readily sticks to the leaves and stems of plants.
13 Its softness reduces wear on application equipment.

CRYSTAL MOUNT CO. FOR MINING & SUPPLYING (limited) provide talc rock in different types with high quality and commitment in delivery.

Also known as ground quartz and silica flour, is produced by grinding high-purity quartz, quartzite, sandstone, or silica sand to finer than 45 micron. Air separation is used as required to remove kaolin, mica, feldspar, or calcite impurities.
we can crush also reach 45 micron with magnetic separation
Uses:
1- glass industry
2- lenses industry
3- television, radio, computer, radar, transmission machine industry
4-pure quartz for photocells
5- semi conductor industry
6-Cleaners
7-Paint
8-cramics: Low-iron ground silica, typically -200 mesh, and calcined silica are used in whiteware formulations to facilitate drying of the body, to control expansion characteristics and compatibility between the body and glaze to prevent crazing, and to provide whiteness and acid resistance.
10-Coatings Ground quartz and novaculite are used as extender pigments because of their low binder demand, which allows high loadings.
11-Rubber Finer (<0.025 micrometer) precipitated silica is the only fully reinforcing alternative to carbon black for general rubber compounding. Most of the precipitated silicas used in rubber are reinforcing grades rather than the coarser extending grades. Precipitated silica is used in compounds designed to be translucent or colored, and in general compounding to promote abrasion resistance, cut growth resistance, tear strength, elastomer-to-textile adhesion, and resistance to heat aging.
12- Plastics: are used as thixotropes in unsaturated polyester resins and gel coats and in epoxy resins. Fumed and precipitated silicas are used as thixotropes in PVC plastisols. used as ant blocking and antislip agents by temporarily absorbing plasticizers that can cause tack and by providing an imperceptible surface roughness. They are used as matting or flatting agents and as plate-out agents in highly plasticized compounds.
