Chromite mining in world and India

Chromite mineral --
=============


Chromite is a metallic mineral containing chromium, iron and oxygen. It is valuable used for stainless steel and other alloys or used for rarefactory functions.
             It is characterised by high melting points,  corrosion resistance, oxidising agent for tanning.
         However, chromite deposits that are large enough for mining are generally found in: 1) stratiform deposits (large masses of igneous rock such as norite or peridotite that slowly crystallized from subsurface magma); 2) podiform deposits (serpentines and other metamorphic rocks derived from the alteration of norite and peridotite); and, 3) beach sands (derived from the weathering of chromite-bearing rocks).
   Major chromite producers are (rankwise) in the world :----
1) South Africa
2) Turkey
3) Kazakhstan
4) India

Major chromite reserves in the world are :--
    1) Kazakhstan
    2) South Africa
    3) India
    4) turkey

Major consumer of chromite are :--
   1) China
   2) Japan
   3) europe
   4) south Korea.

In India 97% of chromite production comes from Odisha and rest from karnataka and Maharashtra. Reserves of chromite also in nagaland, manipur, A.P., telengana, but 96% reserves of chromite only from odisha state of SUKINDA valley. Mahagiri hills, kathpal, Baula  Nausahi, Kaliapani..mainly 3 districts : jajpur, dhenkanal, keionjhar .
