REPORT ON ENVIRONMENTAL ISSUES OF CHROMITE

Opencast chromite mining generate enormous quantities of overburden (OB). The stripping ratio varies from 1:5 to 1:10. Unless managed properly, run offs from the OB dumps have the dual potential of polluting the water bodies by siltation and leaching of Cr(VI). Dust generation: Huge amounts of dust is released during mining, stacking and

(PDF) An overview of chromite mining in Sukinda valley in

It is well known that opencast chromite mining generates huge volumes of seepage water. This water seeps into the ground of the quarry. It dissolves the chromium. The chromium in trivalent stage Cr(III) turns into the hexavalent Cr(VI) form due to complex reactions (including oxidation). Hexavalent chromium is more soluble in water than any

Jan 01, 2016 Wastes of Chromite Mining. Chromite mining wastes have the potential to cause serious environmental contamination. This occurs in places around the world where these wastes are inadequately managed. Overburden is an important type of mine waste. Overburden includes the soil and rock that is removed to gain access to ore deposits at open cast mines.
