Iron ore flotation is generally concerned with the separation of the iron oxide minerals from those containing silica. For these ores the flotation method employed may be that which recovers iron minerals in the froth (direct flotation), or alternatively, that by which the siliceous gangue is contained in the froth product (reverse flotation).
