  • Iron ore Wikipedia

    Lowergrade sources of iron ore generally require beneficiation, using techniques like crushing, milling, gravity or heavy media separation, screening, and silica froth flotation to improve the concentration of the ore and remove impurities The results, highquality fine ore powders, are known as fines Magnetite Magnetite is magnetic, and hence easily separated from the gangue minerals andWhen the iron ore is extracted from the mine, it must undergo several processing stages Six steps to process iron ore 1 Screening We recommend that you begin by screening the iron ore to separate fine particles below the crusher’s CSS before the crushing stage A static screen is used to divert the fine particles for crushing This stepThe Six Main Steps of Iron Ore Processing | Multotec Canada12/10/2018· Gravity 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) etc Hence, besides gravity, other factors, such as sizeGravity separation and Ore Beneficiation – IspatGuru
