Environmental Impact of Chromite Mining in Sukinda Valley Chromium exists in two stable states, i.e. hexavalent chromium (Cr+6) and trivalent chromium (Cr+3) of which (Cr+6) is the most toxic form. Trivalent chromium does not induce any harmful effect, when fed in water or food to living organisms.
Sep 24, 2020 Laborers working in the chromite mines are always at a high risk of being affected by Cr (VI) contamination and its toxic effects. Cr (VI) is a proven sensitizer of the skin as well as the respiratory tract.
Understanding the impact of gold mining on local communities before, during and after the life of a mine is a vital part of responsible mining. This includes dealing not only with national governments, but understanding the needs and aspirations of indigenous communities to ensure positive impacts.
Time during 1993 – 94, to assess the health impacts due to chromite mining. This is perhaps the first and by far the only such documented report. A random sample of 188 households, out of a total 373, in the villages near four chromite mining areas in Sukinda (Kamarda, Saruabil, OMC and TISCO) was selected for the study. -.

Potential Toxic Effects Of Chromium Chromite Mining. Chromium-iii is found in the mineral chromite.The main use for chromite ore mined today is the production of an iron-chromium alloy called ferrochrome fecr, which is used to make stainless steel.Extensive chromite deposits have been identified in northern ontario 500 km north-east of thunder bay in the area dubbed the ring of fire.
Poisoning has had toxic effects in workers employed in chromite mines (17). Effluents from the chromite mines, coal mines and coal utilization sites are discharged into various tributaries of the Brahmani river(10). People live in this areas have been found to suffer from toxic effects arising from exposure to chromium.
Apr 23, 2018 A public presentation by Ugo Lapointe of Mining Watch Canada was held April 24 to help answer questions regarding the potential environmental impacts of chromite mining and of a ferrochrome.
Chromium. Chromium (Cr) is a hard, bluish metallic element. The only ore of chromium is the mineral chromite and 99 percent of the world’s chromite is found in southern Africa and Zimbabwe. Geologists estimate that there are about 11 billion tons of mineable chromite ore in the world, enough to supply the current demand for hundreds of years.
