N. Koleli, A. Demir, in Environmental Materials and Waste, 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.
In India, sanctions for chromite mining depend on both the central and state governments. A clear set of rules for obtaining environmental clearances for industrial and infrastructure related projects is prescribed by the Environmental Impact Assessment (EIA) Notification, 1994 issued by the Ministry of Environment and Forest (MoEF).
Jun 30, 2005· Sukinda chromite valley is one of the largest chromite deposits of the country and produces nearly 8% of chromite ore. It greatly contributes towards the economic development but at the same time deteriorates the natural environment. It is generally excavated by opencast mining method.
This section focuses on threats directly associated with raw materials used in chromite industry and its wastes. To facilitate discussions about raw materials used in chromite industry and waste generated, a generalized Cr material flow diagram, from chromite ore mining to end use, is shown in Fig.
Relation to Mining. While China is the leading chromiumconsuming country and the leading stainless steel producer, it is not a large producer of chromite ore. The United States, Kazakhstan, India and South Africa are the largest chromitemining countries in the world.
Jul 22, 2017· Seventy years of intensive opencast chromite ore extraction have resulted in massive holes in the ground, mountains of ''overburden'' (waste rock and soil), toxic water and soil, ruined agricultural fields and large tracts of degraded forestland. And the people have been slowly poisoned over the years, as in many mining areas around the country.
Environmental Quality of the BoulaNuasi Chromite Mine Area in India Mine Water and the Environment, 2011, 30, 191–196 / Springer January 1, 2011. Chromite mining can create hostile conditions for organisms in the surrounding environment.
Residues from mining and chromite processing are often toxic, not only because of the presence of hexavalent Cr (Cr(VI)) but because of the reagents and other waste materials in overburden and wastes.

Chromite forms in deep ultramafic magmas and is one of the first minerals to crystallize. It is because of this fact that chromite is found in some concentrated ore bodies. While the magma is slowly cooling inside the Earth''s crust, chromite crystals are forming and because of their density, fall to the bottom and are concentrated there.
