Mica are sheet silicates historically significant for their ability to be split into large, thin sheets that are uniquely useful for their electrical, thermal, and mechanical properties. They have high electrical and thermal insulating properties; they are resistant to chemical attack; they can be split into transparent or optically flat films; and they can be cut or stamped to shape. Uses of mica: 1- Joint cements: muscovite is used in drywall joint compounds, where it contributes to consistency and workability, smooth surface finish, and resistance to shrinkage and cracking. 2- Coatings Fine-ground, -325 mesh and micronized mica grades are used in paint as a pigment extender and for dry film reinforcement. The inert, platy mica improves suspensi on stability, controls film checking, chalking, shrinkage, and blistering, improves resistance to weathering, chemicals, and water penetration, and improves adhesion to most surfaces. Coarser grinds are used in textured paints, and wet-ground mica is used in high quality exterior house paints. High aspect ratio grades are preferred for porous surface sealers to seal pores, control penetration, and reduce sagging and film cracking. 3- Plastics Finely ground, -325 mesh and micronized micas are used in plastics to improve electrical, thermal, and insulating properties. Mica is considered the most effective mineral for reducing warpage and increasing stiffness and heat deflection temperature in plastics. In general, mica reinforces crystalline better than amorphous polymers. Best results are obtained with nonpolar polymers when mica is pretreated with a coupling agent to improve wetting. Mica is used in both thermoplastics and thermosets. Its largest single use is in polyolefins, even though it requires stabilizers to prevent degradation of polypropylene. 4- Drilling fluids Coarse, hammermilled (+10 mesh) mica is used in waterbased oilwell drilling fluids to prevent fluid loss into porous rock formations.

Calcium carbonate, or CaCO3, comprises more than 4% of the earths crust and is found throughout the world. Its most common natural forms are chalk, limestone, and marble, produced by the sedimentation of the shells of small fossilized snails, shellfish, and coral over millions of years. Although all three forms are identical in chemical terms, they differ in many other respects, including purity, whiteness, thickness and homogeneity. Calcium carbonate is one of the most useful and versatile materials known to man. Uses Paper, Plastics, Paints, and Coatings: Calcium carbonate is the most widely used mineral in the paper, plastics, paints and coatings industries both as a filler and due to its special white color - as a coating pigment. In the paper industry it is valued worldwide for its high brightness and light scattering characteristics, and is used as an inexpensive filler to make bright opaque paper. Filler is used at the wet-end of paper making machines, and calcium carbonate filler allows for the paper to be bright and smooth. As an extender, calcium carbonate can represent as much as 30% by weight in paints. Calcium carbonate also is used widely as a filler in adhesives, and sealants. Personal Health and Food Production: Calcium carbonate is used widely as an effective dietary calcium supplement, antacid, phosphate binder, or base material for medicinal tablets. It also is found on many grocery store shelves in products such as baking powder, toothpaste, dry-mix dessert mixes, dough, and wine. Calcium carbonate is the active ingredient in agricultural lime, and is used in animal feed. Calcium carbonate also benefits the environment through water and waste treatment. Building Materials and Construction: Calcium carbonate is critical to the construction industry, both as a building material in its own right (e.g. marble), and as an ingredient of cement. It contributes to the making of mortar used in bonding bricks, concrete blocks, stones, roofing shingles, rubber compounds, and tiles. Calcium carbonate decomposes to form carbon dioxide and lime, an important material in making steel, glass, and paper. Because of its antacid properties, calcium carbonate is used in industrial settings to neutralize acidic conditions in both soil and water Element CaCo3 99.20 MgCo3 0.20 Fe2O3 0.01 HCI 0.20 Whiteness 96.30 Yellowness 0.70 Size : 20-8 Micron

Talc stone is known for being the softest mineral on earth, and can be easily scratched by a fingernail. Talc is not commonly seen in collections, as it is usually uninteresting and fairly common, although a few deeply colored and crystallized examples are known and well sought after. Also very popular are the Talc pseudo morphs. Talc forms some very interesting pseudo morphs after many different minerals, and certain localities are known for the specific minerals replaced by Talc. Health concerns including a rare respiratory disease are known to be associated with Talc in its powder form. Although solid forms of Talc are assumed to be safe, and most concerns are only after prolonged exposure. Uses : Talc is used as a filler, coating, pigment, dusting agent and extender in plastics, ceramics, paint, paper, cosmetics, roofing, rubber and many other products.
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
Sand particles range in diameter from 0.0625 mm to 2 mm. An individual particle in this range size is termed a sand grain. Sand grains are between gravel (with particles ranging from 2 mm up to 64 mm) and silt (particles smaller than 0.0625 mm down to 0.004 mm). we can reach up to 45 micron milled sand with magnetic separation uses • Beach nourishment: Governments move sand to beaches where tides, storms or deliberate changes to the shoreline erode the original sand. • Brick: Manufacturing plants add sand to a mixture of clay and other materials for manufacturing bricks. • Cob: Coarse sand makes up as much as 75% of cob. • Mortar: Sand is mixed with cement and sometimes lime to be used in masonry construction. • Concrete: Sand is often a principal component of this critical construction material. • Glass: Sand is the principal component in common glass. • Landscaping: Sand makes small hills and slopes (for example, in golf courses). • Glaze, frit, ceramic, instead of quartz • Paint: Mixing sand with paint produces a textured finish for walls and ceilings or non-slip floor surfaces. • Railroads: Train operators use sand to improve the traction of wheels on the rails. • Roads: Sand improves traction (and thus traffic safety) in icy or snowy conditions. • Sand animation: Performance artists draw images in sand. Makers of animated films use the same term to describe their use of sand on frontlit or backlit glass. • Sand casting: Casters moisten or oil molding sand, also known as foundry sand and then shape it into molds into which they pour molten material.
