CHAPTER II

Mine tailings are the waste material that remains after the economic fraction has been extracted from the mineral ore. Tailings consist of a slurry of ground rock, and water and chemical reagents that remain after processing. The composition of mine tailings varies according to the mineralogy of the ore deposit and how the ore is processed.

Efficient utilization of nickel rich Chromite Ore Processing Tailings

Chromite ore processing tailing, a solid waste generated during the processing of chromite ore, is difficult to recover due to its ultra-fine size. The tailings generated from the process contains valuable chromite and iron-bearing minerals, loss of which is a matter of concern for the ferrochrome industry worldwide.
