Siliceous earth is an inorganic material, which has chemical composition of >80 of amorphous of Silica. This amorphous phase is very rare and used widely in industrial scale because of its high porosity, fine particle size, very low density and its high surface area. Its most chemical and physical features are same as Diatomites which is also an amorphous silica consists of fossilized remains of diatoms, a type of hard-shelled algae therefore. Siliceous earth differs from Diatomites in the mode of origin only and seems to be formed from volcanic ash. Due to these similarities in both materials Siliceous Earth finds similar uses as Diatomites.It is mainly used as filler and filter, heat and sound resistant material and in ceramic industry. Filtration and cleaning of vegetable oils and animal fats and manufactures of medicines are other uses of this mineral. Rajasthan is the only state of India that produces this mineral. In advance applications it is used as carrier for catalysts in chemical processes and for mineral fertilizers and herbicides, pesticides and fungicides in agriculture as well as raw material for refination and filtration and constituent of synthetic molding mass

Quick lime is processed white powder with chemical formula CaO. It is processed by the calcination process of Limestone. Limestone is a naturally occurring sedimentary rock consisting of mainly calcium carbonate, along with some other crystalline forms of Calcium. The calcination Lime Stone is carried out by crushing limestone and burning with coal powder. This calcination results evaporate of CO2 which makes quicklime (CaO). Now it is crushed into powder form of different required sizes. Quicklime can react with water at room temperature and makes Ca(OH)2. The quicklime often ground into fine power by pulverize up to ideal for mixing with additives or other materials. Quicklime can also be hydrated with water (slaking) that results in Hydrated Lime Ca(OH)2.

Gypsum has a variety of crystalline forms in which Dihydrate Calcium Sulfate (CaSO4.2H2O) is common and found in Selenite. On a molecular scale it has a lamellar structure in which a layer of water alternates with two layers of CaSO4; hence it can absorb more layers of water. It has an excellent superiority to absorb and release water molecules.From a chemical point of view it is formed by the reactions of Ca and Sulphate Acid present in sea water and deposited in sedimentary layers on the sea bed. Gypsum is produced from open-cast mines that give up to 75% Gypsum. In gypsum calcium or magnesium carbonate, chlorides, other sulphate minerals, clay minerals or silica are considered as deleterious constituents, so normally screened or washed to remove these fine particles. Washing may be added to improve the quality of the material.The gypsum deposits of Bikaner are well known for POP production, cement and fertilizer Industries. It is natural hydrate of calcium sulfate, and partially the plaster of Paris also. The reserves of Gypsum in Bikaner district are estimated as 40.489 million tones.

Bentonite is naturally occurring hydrated Aluminum Silicate. It has ability to absorb water several times its weight and give thick tropic fluid. Bentonite is an absorbent aluminum phyllosilicate, essentially impure clay consisting mostly of montmorillonite. There are different types of Bentonite, each named after the respective dominant element, such as potassium (K), sodium (Na), calcium (Ca), and aluminum (Al). Bentonite usually forms from weathering of volcanic ash, most often in the presence of water. Bentonite is highly plastic, sticky clay used in pottery both in clay bodies and in glazes.
