In fact there are a number of investigations based on reverse flotation techniques for the separation of quartz particles from hematite fines ( Montes-Sotomayor et al., 1998 , Uwadiale, 1992 , Yuhua and Jianwei, 2005 ).

Iron ore - Wikipedia

Lower-grade 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, high-quality fine ore powders, are known as fines.
