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.

Dolomite is a carbonate mineral composed of calcium magnesium carbonate CaMg (CO3) 2. The term is also used to describe the sedimentary carbonate rock dolostone. we can make the crushed grain size as customer need, there is different analysis Uses Dolomite is used as 1- an ornamental stone, 2- a concrete aggregate, 3- a source of magnesium oxide and in the Pidgeon process 4- for the production of magnesium. 5- It is an important petroleum reservoir rock, 6- a flux for the smelting of iron and steel. 7- Large quantities of processed dolomite are used in the production of float glass. 8- production of frit for glaze. 9- added to soils and soilless potting mixes to lower their acidity and as a magnesium source. 10- the substrate in marine (saltwater) aquariums to help buffer changes in pH of the water. 11- one of the basic raw materials in the manufacture of flat glass, which are added by 12% as magnesium oxide helps add to the speed of the glass melting process. 12- in the manufacture of refractories due to the high melting temperature to 2800 ° C and therefore is used in the ovens foundries in Tlies containers. 13- used in the steel industry as well as used in furnaces making steel oxygen and furnaces arcs electric – 14- is also used in furnaces smelting to reduce the melting temperature of slag

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.
Talc Talc ore is an excellent solid minerals which has found use in many industrial applications to mention few is face powders and all ceramics products etc. 50kg pp woven
