Froth Flotation of Iron Ores

02/01/2012 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 century’s practice in the iron ore industry, froth flotation has been established as an efficient method to remove impurities from iron ore.

Froth Flotation of Iron Ores Publications

In practice, iron ore often contains a few percent SiO. 2, even after repeated magnetic or hydraulic separation, due to the presence of locked siliceous gangue minerals. To further upgrade the concentrate, froth flotation has been established as an efficient method to remove impurities from iron ore in half a century’s practice around the world.

The route of reverse flotation is currently in widespread use in iron ore flotation practice. The majority of studies on reverse flotation of iron ore focused on reagents and reagent scheme [9,10,11,12,13]. The reverse flotation route can be classified into reverse cationic flotation and reverse anionic flotation, based on the collector type. The reverse anionic flotation (flotation of gangue
