Therefore, the flotation method employed depends on whether recover iron minerals in the froth (direct flotation), or alternatively, recover the siliceous gangue (reverse flotation) (Ma, 2012). The evolution of Iron ore beneficiation should be considered of great interest due to fasten rise and establishment.
