Distribution of Minerals in India India is rich in mineral deposits. A wide variety of them are found many parts of India. Iron India has deposits of high grade iron ore. States where iron ore is found: Jharkhand, Orissa, Chhattisgarh, Madhya Pradesh, Goa, Maharashtra and Karnataka. Bauxite Bauxite is found in many states.
Economically the most important rocks because they possess valuable minerals like high grade ironore, manganese, copper, lead, gold, etc. Cuddapah System It covers 30% area of Chhattisgarh. the distribution of this kind of rock system are in plateau of Bagelkhand,Jashpur Samripat,plain of Chhattisgarh and Dandkarnya.
1) Mining copper ore bc the heavy, bulky ore that is extracted from mines is mostly waste. The 2nd step=concentration mills that grind ore into fine particles that produce copper concentrate that is only 25% copper. Copper smelters remove more impurities. Concentration mills &smelters built near mines.
Chalcopyrite is a brassy yellow mineral with the chemical composition CuFeS2, or copper iron sulfide. It is found in most sulfide mineral deposits around the world. Chalcopyrite loses its surface metallic luster and brassyellow color when it weathers, changing to a dull, graygreen color.
There are many types of copper ore found throughout the world. Picture 4 shows the distribution of these deposits. About 80% of all copper extracted comes from sulphide ores. A typical ore contains only 0.5% to 2.0% copper. It is a measure of the value of copper that it is worth extracting it from such small concentrations. The ore is a mixture
The performance of the Copper Ore Mining industry largely depends on the world price of copper, global copper production volumes, the value of the Australian dollar, and downstream demand trends. Lower global copper prices, which are set in US dollars, have largely been offset by a weaker Australian dollar over the past five years.
Brazil produced 400Mt of iron ore in 2012 accounting for about 13% of the worlds total, while its iron ore reserves estimated at 31bt containing 16bt of iron, are the worlds second biggest. The countrys iron ore deposits are mostly concentrated in the states of Para and Minas Gerais.
Because of its properties, singularly or in combination, of high ductility, malleability, and thermal and electrical conductivity, and its resistance to corrosion, copper has become a major industrial metal, ranking third after iron and aluminum in terms of quantities consumed.
DISTRIBUTION OF MINERALS: IN ASIA : in Asia, large iron ore deposits occur mainly in China, Indian and Siberia. the continent produces large share of worlds tin. China, Malaysia and Indonesia among the world's leading tin producing countries. Asia also has deposits of Manganese, bauxite, Nickel, gold, lead zinc zinc and copper.
