Chromite is the principal ore of Cr, available in large capacity in Sukinda, in the Jajpur district of Odisha (India) and contains ≅97% reserves in the country. Open cast mining is the general practice in the area, which generates excessive material that subsequently result in leaching of Cr(VI) salt into the water table (Mishra and Sahu 2013).
Mining of chromite deposits is being carried out both by open-pit and underground mining. Early mining of chromite was on a small-scale and was relatively straightforward from outcrops or to shallow depths followed by hand sorting. With the increased demand, conventional open-pit mining and mechanical underground mining became necessary. ...
