The carbonate mineral calcite is a calcium carbonate corresponding to the formula CaCO 3  and is one of the most widely distributed minerals on the Earth's surface.   Calcite crystals are hexagonal-rhombohedral, though actual calcite rhombohedrons are rare as natural crystals. However, they show a remarkable variety of habit including acute to obtuse rhombohedrons, tabular forms, prisms, or various scalenohedrons.   At Ashapura China Clay, processed or refined calcite is available in white powder form, granule cum powder form, and in lumps form. The various grades and their applications are:

kaolin or china clay is a natural mineral found in partly decompo-sed granite, an igneous feldsparic rock. Chemically, kaolin is a hydrated aluminium silicate containing al 2 o 3 .2sio 2 .2h 2 o.   kaolin was first discovered in the mountainous province of kiangsi, china in a.d. 500. The word "kaolin" derives from the chinese character 'kao lin' which means high ridge. It was first used by the chinese to make high quality porcelain.   at ashapura china clay, processed or refined kaolin is available in white powder form, granule cum powder form, and in lumps form. The various grades and their applications are:

  The chemical compound silica, also known as silicon dioxide, is the oxide of silicon, chemical formula SiO 2 . Siliceous is an adjective meaning "referring to silica".   Silica is found in nature in several forms, including quartz and opal. In fact, it has 17 crystalline forms. The most common constituent of sand in inland continental settings and non-tropical coastal settings is silica, usually in the form of quartz because the considerable hardness of this mineral resists erosion. However, the composition of sand varies according to local rock sources and conditions.   At Ashapura China Clay, processed or refined silica sand is available in white powder form. The various grades and their applications are:

Talc is a metamorphic mineral resulting from the metamorphism of magnesian minerals such as pyroxene, amphibole, olivine and other similar minerals in the presence of carbon dioxide and water. This is known as talc carbonation and produces a suite of rocks known as talc carbonates.   It occurs as foliated to fibrous masses, its monoclinic crystals being so rare as to be almost unknown. It has a perfect basal cleavage, and the folia are non-elastic, although slightly flexible. It is sectile and very soft, with a hardness of 1 (Talc is the softest of the Mohs' scale of mineral hardness). It has a specific gravity of 2.5–2.8, a waxlike or pearly luster, and is translucent to opaque.   At Ashapura China Clay, talc is available in white powder form. The various grades and their applications are:

  PYROPHYLLITE   Pyrophyllite is a phyllosilicate mineral species belonging to the clay family and composed of aluminium silicate hydroxide: AlSi 2 O 5 OH.   Pyrophyllite occurs in phyllite and schistose rocks, often associated with kyanite, of which it is an alteration product. Pale green foliated masses, very like talc in appearance, are found at Beresovsk near Ekaterinburg in the Urals, and at Zermatt in Switzerland.   At Ashapura China Clay, pyrophyllite is available in powder form.  

  WHITE BENTONITE   Bentonite is an absorbent aluminium phyllosilicate generally impure clay consisting mostly of montmorillonite, (Na, Ca) 0.33 (Al, Mg) 2 Si 4 O 10 (OH) 2 ·(H 2 O) n .   The absorbent clay was given the name bentonite by an American geologist sometime after its discovery in about 1890 - after the Benton Formation (a geological stratum, at one time Fort Benton) in eastern Wyoming's Rock Creek area.   Other modern discoveries include Montmorillonite discovered in 1847 in Montmorillon in the Vienne prefecture of France, in Poitou-Charentes, South of the Loire Valley and Pascalite discovered in about 1830 by French-Canadian fur trapper Emile Pascal atop the 8600-foot high Big Horn Mountains in Wyoming, USA.   At Ashapura China Clay, processed or refined white bentonite is available in powder and in lumps form.

Dolomite is the name of both a carbonate rock and a mineral consisting of calcium magnesium carbonate (CaMg(CO 3 ) 2 ) found in crystals.   Dolomite rock (also dolostone) is composed predominantly of the mineral dolomite.   Dolomite was first described in 1791 as the rock by the French naturalist and geologist, Déodat Gratet de Dolomieu (1750-1801) for exposures in the Dolomite Alps of northern Italy.   At Ashapura China Clay, dolomite is available in white powder form.
