Chromite in podiform deposits form as anhedral grains. The ores seen in this type of deposit have nodular texture and are loosely-packed nodules with a size range of 5–20 mm. Other minerals that are seen in podiform deposits are olivine, orthopyroxene, clinopyroxene, pargasite, Na-mica, albite, and jadeite.

Efficient extraction of slowly-released Cr(vi) from nano-sized ion
Residual unreacted Cr(VI) incorporated in ferrous-sulfate-reduced chromite ore processing residue (rCOPR) can be slowly released during deposition, posing a significant threat to the environment. Recent studies indicate that such Cr(VI) mainly exists within the nano-sized ion channels of ettringite, forming Cr(VI)–ettringite.

Ecological and human health risk assessment of chromite ore
In this study, ecological and human health risk assessment (HHRA) of the subsurface environment was performed due to the presence of six different contaminants, i.e., Cr(VI), U, F-, As, NO 3-, and Mo, in the proximity of chromite ore processing residue (COPR) dumping sites of Northern India. The analysis covered a probabilistic risk Chromium VI is the most dangerous form of chromium and may cause health problems including: allergic reactions, skin rash, nose irritations and nosebleed, ulsers, weakened immune system, genetic material alteration, kidney and liver damage, and may even go as far as death of the individual. There is, however, no established limit for Chromium and its negative effects on the environment Case

environmental chromium pollution on wildlife and we did not find any information directly relevant to potential impacts of chromite mining and ferrochrome production on terrestrial wildlife. Hexavalent chromium can negatively impact soil ecology in a variety of ways such as decreasing soil micro-organism presence, diversity and function.1. Introduction. Chromite ore processing residue (COPR) is an industrial waste generated during the extraction of Cr(VI) from chromite ore using the high-temperature lime-based roasting process [[1], [2], [3]].When COPR undergoes weathering reactions during the deposition process, it would release highly toxic and mobile Cr(VI) Identification of Cr(VI) speciation in ferrous sulfate-reduced chromite

Chromite mining pollution, environmental impact, toxicity and
Chromite mining activities are indispensable for production of goods and services. Sukinda is a major mining site of Odisha, India, polluted by chromium, which is highly toxic in its hexavalent form. The Sukinda valley is a rich source of chromites, amounting to almost 95% of Cr available in India, and is the fourth most polluted site Chromite ore processing residue (COPR) is a waste byproduct of chromate production that contains high levels of hexavalent chromium (Cr(VI)). Although the high temperature chromite process was banned in several countries, its legacy still exists at numerous contaminated sites.
