Froth Flotation of Iron Ores

Jan 02, 2012· With the depleting reserves of high grade iron ore in the world, froth flotation has become increasingly important to process intermediate and low grade iron ore in an attempt to meet the rapidly growing demand on the international market. In over half a centurys practice in the iron ore industry, froth flotation has been established as an efficient method to remove impurities from iron ore.
