Low grade Iron Ore Beneficiation and the Process of
Sep 25, 2018· The reasons for choosing jigging for the iron ore beneficiation over other processes include (i) relatively easy separation, (ii) beneficial tradeoff between operating cost and reduced yield relative to dense medium processes, (iii) ability to treat ores requiring cut densities higher than a density of 40, and (iv) physical characteristics ofGravity separation is a physical process which consists of the separation of different mineral types in the ore from one another based on differences in their specific gravities using the force of gravity, which can be influenced by one or more of other forces such as centrifugal force, resistance to motion by a fluid (eg air, water) etcGravity separation and Ore Beneficiation – IspatGuru
