Introduction to Mineral Processing or Beneficiation

Ore is a term used to describe an aggregate of minerals from which a valuable constituent, especially a metal, can be profitably mined and extracted. Most rock deposits contain metals or minerals, but when the concentration of valuable minerals or metals is too low to justify mining, it is considered a waste or gangue material.

Journal of Environmental Analytical Chemistry

Low-grade deposits and the fines resulting in the mining operations cannot be economically used. Therefore, beneficiation of low grade and finely disseminated chromite ores is becoming important, due to the shortage of high grade ore reserves [1,2]. High grade chromite ore commonly was mined from Ingassana hills deposits in the Blue Nile region.
