Chromite Ore Processing Residue (COPR) is the byproduct of chromate production process, which contains a large amounts of Cr (VI). The present work developed a new technique to treat COPR, and the process involved mixing the COPR with rice straw followed by pyrolysis. It was found that the gaseous organic fraction generated during …
The rate of chromite ore extraction, although mining is being carried out in this region since independence, has been amplified during 1980's in consequence of its sky-scraping demand and subsequently its surrounding environment is also deteriorating day by day.
