The exploitation of the ore is carried out through open cast mining method since the last few decades. In the process, the overburden and ore dumps are stored on ground surface, where leaching of chromite and other toxic element takes place particularly during monsoon seasons. This leachate may cause threat to groundwater in the vicinity.

The choice of mining method for extracting ore from the earth's surface depends on various factors related to the ore itself. These factors include whether the ore is stratiform or podiform, its grade (whether high or low), and its depth below the surface.Most chromium ore is found abundantly in stratiform deposits within layered intrusions, with notable …
