China clay is one of the purest of the clays, composed chiefly of the mineral kaolinite usually formed when granite is changed by hydrothermal metamorphism. China clays have long been used in the ceramic industry, especially in fine porcelains, because it can be easily molded, have a fine texture, and are white when fired. These clays are also used as filler in making paper.Its occurs in the deposits in the form of china clay rock, a mixture of up to 15 per cent china clay and up to 10 per cent mica, and the remainder being quart.

Its usage are : It is the heart of several industries like potteries, tiles, ceramics, glass and others.As extender and filler in Paints, Paper, Detergents, Bakelite Powder and in Rubber industries etc.

Calcite (also known as Calium Carbonate and Snowhite Powder) is the one of the most common minerals on earth. It occurs in a seemingly unlimited variety of shapes and colors. It constitutes a major portion of many of the earth's rocks. Chemically it is calcium carbonate, CaCO3, but it frequently contains manganese, iron, or magnesium in place of the calcium. It crystallizes in the hexagonal system, its crystals being characterized by highly perfect cleavage. Calcite also occurs in a number of massive forms, in which it may be coarsely to finely granular (as in marble), compact (as in limestone), powdery (as in chalk), or fibrous.

It crystallizes in rhombohedron class. It is also known by the name calcspar. It is white in color but is also found in various shades like pink, brown etc., depending upon the impurities present. Its composition is identical to that of limestone but the latter occurs as sedimentary beds. There is another mineral, aragonite, of the same chemical composition. It crystallizes in orthorhombic system. It is, however, an unstable mineral, found mainly associated with gypsum beds and the tests of reef-building corals. It is not found in the same large quantity as that of calcite.

Its Usage are : Rubber, Paints, Plastic Industries,Important filler in Ceramic and Tiles Industries, Rigid PVC Pipes, footwear, cables & leather clothes,Medicinally as an inexpensive dietary calcium supplement.

Pharmaceutical industry as an inert filler for tablets and other pharmaceuticals.In the production of toothpaste and is also used in homeopathy as one of the constitutional remedies. Also, it has seen resurgence as a food preservative and color retainer Used in variety of construction chemical products, water proofing compounds etc.

Available in Lumps and Powder for the following industries; Ceramics, Paint, Paper, Plastic, Soap & Cosmetic. Its Particle Size: 300 - 1800 Mesh and Whiteness: 90 - 97%

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.

Dolostone (dolomite rock) is composed predominantly of the mineral dolomite with a stoichiometric ratio of 50% or greater content of magnesium replacing calcium, often as a result of diagenesis. Limestone that is partially replaced by dolomite is referred to as dolomitic limestone, or in old U.S. geologic literature as magnesian limestone.

Its usage are : Dolomite is used in paints Dolomite is chosen for many construction and building product applications due to its increased hardness and density. Asphalt and concrete applications prefer dolomite as a filler for its higher strength and hardness. Dolomite is also widely used in a number of applications as a source of magnesium, such as glass and ceramics industry, as well as a flux agent in steel making. Agro-based industry use dolomite for agricultural pH control. The chemical industry uses the mineral dolomite in making magnesium oxide (MgO) used in pharmaceuticals.

Indutrial Applications are:

White Detergent.
Plastics & Cables.
Rigid PVC Pipes.
Paints.
Other Thermoplastics.
Polyester Glass Fibre Reinforcements.
Ceramics.
Powder Coating.
Leather Cloth.

Available Particle Size: 400 Mesh for Paints, Rubber, Plastic etc.

Magnesite is a Carbonate of Magnesium (MgC03). Raw Magnesite as such is not used in any industry except in Chemical Industry for the manufacture of Sulphates (Epsam Salt). A Small quantity of pure magnesite free from Iron is used in the glass industry. Magnesite after dead-burning is an ideal Mineral for manufacture of Super Duty Basic Refractory Bricks largely used in the Steel Industry. Lightly Calcined Magnesite (LCM) containing 2-10% CO2 called Caustic Magnesite is used for a wide variety of indutsrial application, the most important being in the manufacture of Oxychloride or Sorel Cement, Pulp and Paper processing chemicals, Rayon and in production of Fertiliser and Animal Feed Stuffs. Specially prepared light magnesium carbonate is added to Rubber for reinforcing and stiffening. It is also used in the manufacture of Magnesium Metals. The grinding stones for rice husk milling is made from emery Caustic-Calcined Magnesia and Magnesium Chloride.

In addition to above Magnesite is considered to be potential for use in Uranium processing, Water treatment and stack gas scrubbing etc.

Its availability is:

MgO----46% min
Fe----0.6% max
SiO----1 % max
CaO-----3% max
It's Physical size: 20 - 200mm : 100%

Barium sulfate (or sulphate) is the inorganic compound with the chemical formula BaSO4. It is a white crystalline solid that is odorless and insoluble in water. It occurs as the mineral barite, which is the main commercial source of barium and materials prepared from it. The white opaque appearance and its high density are exploited in its main applications Almost all of the barium consumed commercially is obtained from barite, which is often highly impure. Barite is processed by carbo thermal reduction (heating with coke) to give barium sulfide:

BaSO4 + 4 C → BaS + 4 CO

In contrast to barium sulfate, barium sulfide is soluble in water and readily converted to the oxide, carbonate, and halides. To produce highly pure barium sulfate, the sulfide or chloride is treated with sulfuric acid or sulfate salts:

BaS + H2SO4 → BaSO4 + H2S

Barium sulfate is commonly used as filler for plastics to increase the density of the polymer in vibration mass damping applications. In polypropylene and polystyrene plastics, it is used as filler in proportions up to 70%. It has an effect of increasing acid and alkali resistance and opacity. As barium sulfate has high burning point and is insoluble in water, it is used as a coating material in casting of copper anode plates. The anode plates are cast in copper molds, so to avoid the contact of the liquid copper and the solid copper mold, a solution of barium sulfate in water is used as a coating material on the mold surface. Thus when the liquid copper solidifies in form of an anode plate it can be easily released from its mold.
