Chromite mining pollution, environmental impact, toxicity
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 classify it as a resource and to design the mine and chrome ore beneficiation plant. Extensive confirmation drilling, core logging and sampling and metallurgical test work was carried out during the latter part of 2005 and much of 2006. The Voskhod deposit was shown to have an indicated chrome ore content of 19.51 millionTHE DEVELOPMENT OF THE VOSKHOD CHROME

The use of the AOD process has allowed lower grade (hlgh-iron 'charge chrome') ores to be used in steelmaking as well as the traditional high-chromium, 'metallurgical grade' ores. This development is the main reason for the expansion of the chromite mining industry in South Africa, the high-iron stratiform deposits being Abstract. Chrome ore properties play a critical role in various pelletisation subprocesses (grinding, filtering, pelletisation and sintering) and slight variation in ore properties significantly affect the whole pelletisation process. Three ore samples (sample-A, B and C) were collected from different working faces of a chromite ore mine.Study the effect of chromite ore properties on pelletisation process

Common Chrome Ore Beneficiation Process and Equipment
The selectability of chrome ore is affected by many factors, such as the grade, purity, purity of immersion, and the composition and quantity of symbiotic gangue minerals. The chromium ore with different properties will be processed by different mineral beneficiation technologies. At present, the chrome ore beneficiation process often used We are Asia’s largest Chrome Ore deposit mines and use smart mining techniques to extract high quality Chrome Ore, sustainably. We mainly produce 3 grades of Chrome Ore High Grade Chrome Ore (>52% Cr2O3 Grade), Medium Grade Chrome Ore (40-52% Cr2O3 Grade) and Low Grade Chrome Ore (<40% Cr2O3 Grade), and supply Chrome Ore to all Tata Steel's Sustanable Chrome Ore Depost Mines Tata
