iron ore blue dust beneficiation process

  • BENEFICIATION OF IRON ORE

    Appropriate beneficiation process has to be advanced to reduce the waste generation in mines and for the sustainable growth of the iron ore industry some. Major reason for difficulty in beneficiation of BHJ is revealed from characterization studies which show the intergrowth of haematite and quartz.

  • Ore Beneficiation an overview ScienceDirect Topics

    Crushing and screening is typically the first step of iron ore beneficiation processes. In most ores, including iron ore, valuable minerals are usually intergrown with gangue minerals, so the minerals need to be separated in order to be liberated. This screening is an essential step prior to their separation into ore product and waste rock.

    Data has been reported regarding availability and quality of iron ore fines including blue dust. It has been shown that in many cases beneficiation or pretreatment of the ore is necessary before use. As economic consideration is the deciding factor in the selection of the beneficiation technique a term 'Economic Index' has been introduced to evaluate the performance of beneficiation process.
