Detrital iron deposits (DID) are located adjacent to the Precambrian bedded iron deposit (BID) of Joda near the eastern limb of the horseshoeshaped synclinorium, in the Bonai–Keonjhar belt of Orissa. The detrital ores overlie the Dhanjori Group sandstone as two isolated orebodies (Chamakpur and ...
The chemical composition of the soil also changes in the mining area. It becomes a desertlike environment where nothing grows. Jharkhand is a state in eastern India .
Rareearth element Rareearth element Minerals and ores: The content of the individual rareearth elements varies considerably from mineral to mineral and from deposit to deposit. The minerals and ores are generally classified as "light" or "heavy"; in the former group most of the elements present are the lightatomicweight elements (, lanthanum, cerium, praseodymium ...
The hematite ore or redochre is called 'oxide of iron'. It has ferrous content ranging from 60 to 70%. It is mainly found in the Dharwad and Cuddapah rocks of the Peninsular India. It is massive, hard, compact and lumpy ore with reddish or ochre red in colour.

Manganese is a chemical element with the symbol Mn and atomic number 25. It is not found as a free element in nature; it is often found in minerals in combination with is a transition metal with a multifaceted array of industrial alloy uses, particularly in stainless steels.
Mechanical: Mica is highly tough, having high tensile strength, elastic, and along with being flexible. It has immense compression power and can be machined, diepunched, or hand cut. Mica from India. The best known fact is Mica is produced in vast proportions in India. In reality, India is one of the foremost suppliers of mica to the world.
Metallic minerals present a metallic shine or lustre in their appearance. They contain metals in their chemical composition. These mineral are a potential source of the metal which can be got through mining. These minerals contain metal in raw form. Iron ore, bauxite, manganese ore are examples of metallic minerals.
Minerals are distinguished by various chemical and physical properties. Differences in chemical composition and crystal structure distinguish the various species . Within a mineral species there may be variation in physical properties or minor amounts of impurities that are recognized by mineralogists or wider society as a mineral variety .
ore denotes hard massive ores, flaky denotes flakyfriable ores, waste denotes shales while mixed ore is the term used for a mixture of different varieties of ores). Table 1 Mineral composition of different iron ores and Banded Hematite Jasper Ore type Ore minerals Gangue minerals Hard ore or Hard massive ore Hematite replaced by goethite.
Bauxite. Bauxite is not a mineral, but rather a group of aluminum oxide s. The term is generally used to describe the economically important mixture of these minerals, which form a mass of the individually classified members of Gibbsite, Boehmite, and Diaspore. Bauxite does not make aesthetic or interesting specimens as far as collectors are...
China clay (kaolin) consisting dominantly of kaolinite is one of the most sophisticated industrial minerals with a host of applications, viz., in ceramics, refractories, paper coating, filler for rubber, insecticides, cement, paint, textiles, fertilizers and others including abrasives, asbestos products, fibreglass, chemicals, cosmetics, pharmaceuticals, electrical ware, foundry and glass.

chemical composition is a mineral. Minerals are not evenly distributed over space. They are concentrated in a particular area or rock formations. Some minerals are found in areas which are not easily accessible such as the Arctic ocean bed and Antarctica. Minerals are formed in different types of geological environments, under varying conditions.
Iron is commonly found in the Earth's crust in the form of an ore, usually an iron oxide, such as magnetite or hematite. Iron is extracted from iron ore by removing the oxygen through its combination with a preferred chemical partner such as carbon which is then lost to the atmosphere as carbon dioxide.
