 · Size classifiion will require screening, desliming and cycloning. In the case of a lowergrade iron ore, the beneficiation process includes activities such as crushing, milling, gravity or heavy media separation, screening and silica froth flotation. These activities will help improve the concentration of the ore and remove impurities.

Such baghouses tested in the mineral processing industry consistently reduce emissions to less than gram per dry standard cubic meter (g/dscm) ( grains per dry standard cubic foot [gr/dscf]), with an average concentration of g/dscm ( gr/dscf).

 · By adding a beneficiation agent to an aqueous ore slurry, then applying a gravitational force to separate, or partition, the slurry into a beneficiary and a gangue, a number of quantifiable benefits are observed. These include increased alumina content and reduced silica content in the beneficiary solids as compared to the starting ore.
