kaolin, also called china clay, soft white clay that is an essential ingredient in the manufacture of china and porcelain and is widely used in the making of paper, rubber, paint, and many other products.
In its natural state kaolin is a white, soft powder consisting principally of the mineral kaolinite, which, under the electron microscope, is seen to consist of roughly hexagonal, platy crystals ranging in size from about 0.1 micrometers to 10 micrometers or even larger. These crystals may take vermicular and booklike forms, and occasionally macroscopic forms approaching millimeter size are found. Kaolin as found in nature usually contains varying amounts of other minerals such as muscovite, quartz, feldspar, and anatase. In addition, crude kaolin is frequently stained yellow by iron hydroxide pigments. It is often necessary to bleach the clay chemically to remove the iron pigment and to wash it with water to remove the other minerals in order to prepare kaolin for commercial use.
When kaolin is mixed with water in the range of 20 to 35 percent, it becomes plastic (i.e., it can be molded under pressure), and the shape is retained after the pressure is removed. With larger percentages of water, the kaolin forms a slurry or watery suspension.

Gypsum (CaSO4.2H2O) is a naturally occurring mineral mined from deposits formed by ancient sea beds as a raw material, white when pure, but commonly grey, yellow, red or brown, owing to impurities. The anhydrous form (CaSO4), anhydrite, is common. We are enlisted amongst the topmost INatural Gypsum Importers and Exporters from India.
Applications:
Gypsum has many industrial applications in its raw or Calcined forms, especially in the building and construction industries. Uses of Raw Gypsum are principally as:
- a retarder for Portland cement
- a fertilizer or soil conditioner
- mineral filler
- oxidizing agent in glass manufacture or other industrial applications.
Most gypsum is calcined and used in the manufacturing of plaster products. Wallboard and plaster requires gypsum contents greater than 85%, although producers prefer a minimum of 94–95% along with whiteness in color. The major consumers of the Gypsum at present are Cement Industry. By weight about 4% to 6% Gypsum in crushed condition is utilized in Portland Cement Manufacture after mixing with cement/clinker. Gypsum acts as a retarder and controls the setting time of cement.
Imported Gypsum from Iran:
Natural Gypsum is one of the most superior qualities and consistent material available for Import and Export. Natural Gypsum has adequate whiteness, high purity as well as it is low in cost which makes it absolutely feasible for white cements as well as Plaster Of Paris manufacturing and for the Cement Industry all together. One more important quality that distinguishes Natural Gypsum from others is its hardness which is less as compared to other sources and allows different industries to easily grind the same for processing into final product which in turn results in to reduced power consumption for manufacturing industries.
