Bentonite is one the two naturally occurring mineral with highly plastic clay containing average 85 % clay mineral, montmorillonite group with decolorizing and absorbing properties. Bentonite has inherent bleaching properties like fuller’s earth which is giving it a great commercial importance. There are two types of Bentonite: 1.Swelling type or Sodium Bentonite which is referred to as Bentonite 2.Non Swelling type or Calcium Bentonite which is referred to as Fuller’s Earth.
The commercial importance of bentonite depends on its physicochemical properties rather than its chemical composition. Excellent plasticity, lubricity, high dry-bonding strength, high shear and compressive strength, low permeability and low compressibility make bentonite commercially viable
Silica sand is one of the most common varieties of sand found in the world. It is used for a wide range of applications. Granules of Minerals or Rocks broken down technically between about one-sixteenth of a millimeter to two millimeters in diameter, falling between silt and gravel in the spectrum of sizes. Mineral quartz over the years, through the work of water and wind has been broken into tiny granules and these granules can be used for many different purposes, and can be found in most non-tropical regions of the world. There are many varieties of sand in the world, each with their own unique composition and qualities.
Silica in bauxite is mainly found in the form of Kaolinite and quartz. Hematite, Goethite, Anatase, Rutile are the other mineral impurities presents in minor or traceable amounts in Bauxite. Some other gangues of minerals presents in some type of Bauxites are chamosite, pyrite, siderite, ilmenite, sphene, calcite and dolomite. More than 99% Bauxite chemical composition constitutes Al2O3, Fe2O3, SiO2, TiO2 and Loss on Ignition, the rest is contributed by FeO, CaO, MnO, MgO, K2O, Na2O and P2O5. Silica (SiO2) mainly presents in Bauxite in form of kaolinite and quartz respectively known as “reactive” and “free” silica.
In the Indian continent, under different environmental conditions and in different geological processes manganese taken place but the sedimentary mode of formation far outweighed other methods such as supergene enrichment etc.. These manganese ores have been selectively exploited either for direct use or for sweetening the otherwise available phosphor-rich ores. Favorable geological and geomorphological settings, existing well connected rail and road links, easy amenability of ores to beneficiation and liberal Govt. policies make the exploitation of Indian manganese deposits practically a no risk proposition.
Stainless and some ordinary steel industry up to some extent use chrome along with nickel and cobalt as alloying elements. Chrome ore or concentrate is further converted to Ferro Chrome or Charge Chrome in Induction furnaces. Charge Chrome is directly added to molten hot metal (steel).
India bestowed with huge quantities of Coal & Lignite and is 7th largest in the World. The deposits in India have primarily high ash and low GCV. The main disadvantage of Indian coal is hardness and its abrasiveness and it is not perfect for boilers and other machineries. It has necessitated use of imported coal for pure use or blended use. India has scanty deposits of Coaking Coal which is essential for Iron/Steel making and in other metallurgical sectors too. Thus India imports huge quantities of Coking Coal from countries like Australia, New Zealand, South Africa and Indonesia.
