    Separation Of Silica Fom Iron Ore

    Jan 01, 2015 The principal separation in iron ore beneficiation, therefore, is between the iron minerals, hematite andor magnetite, and silica, principally in the form of quartz. The use of flotation, either alone or in combination with magnetic separation, has been well established as an efficient method for rejecting silica from these iron ores.
