the iron ore and also

The total recoverable iron ore in the country are about 10,052 million tons of haematite and 3400 million tons of magnetite. They are mainly distributed in Madhya Pradesh, Karnataka, Jharkhand and Orissa. Minor resources are, of course, distributed in Orissa, Bihar, Goa, Mahara..

The earth's crust contains several mineral ores such as haematite, pyrite, bauxite, dolomite, etc. The ores can be used refined into various metals like iron, copper, aluminium, zinc, manganese, etc. The earth's crust also contains many non - metallic ores s..

Iron is the most abundant metal which occurs in the earth's crust. There are two forms of iron - cast iron and wrought iron - cast iron is the least pure form of iron whereas wrought iron is the purest form of iron. The..

Iron is quite reactive, so it is not found in free state in nature. In the combined state, iron is found in the form of oxide, carbonate and sulphide. Iron occurs in the form of its sulphide in iron pyrites. It is not used commercially for the extraction beca..

In this process, heating is done with the help of a carbon arc. The electrodes are held vertically and the charge (cast iron, scrap iron and iron ore) and lime mixture, is held in between. The furnace is lined with dolomit..

The first magnetic phenomenon observed were those associated with naturally occurring magnets, fragments of iron ore found near the ancient city of Magnesia. These attracted unmagnetised iron. The attraction was maximum at certain regions of the magnet called the..

It is believed that around 2000 BC the Chinese had already discovered the magnetic property of natural iron ore. In a part of Turkey formerly called Magnesia, there are deposits of an iron one which has the property of attracting iron. As this oreh..
