Froth Flotation of Iron Ores

With the depleting reserves of highgrade iron ore in the world, froth flotation has become increasingly important to process intermediate and lowgrade iron ore in an attempt to meet the rapidly growing demand on the international market. In over half a century''s practice in the iron ore industry, froth flotation has been established as an efficient method to remove impurities from iron ore.

The flotation of molybdenite seemed to be less influenced by xanthate than by kerosene, while that of chalcopyrite showed the opposite. The optimum concentration of sodium sulfide for separation was 0.03 mol/L, which rejected 83% chalcopyrite and recovered 82% molybdenite in the single mineral flotation.
