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. In this chapter, the industrial practice and fundamental research activities of iron ore flotation are reviewed.

The main objective of iron ore flotation is to upgrade the concentrate by removing silicates and/or phosphorus-containing minerals. The use of silica flotation has increased in recent decades. The trend will continue as more complex ores have to be mined and higher-grade iron ore concentrates with fewer impurities are requested by the steel industry.

In the mining industry, the plants where flotation is undertaken to concentrate ore are generally known as concentrators or mills. For froth flotation, the ground ore is mixed with water to form a slurry and the desired mineral is rendered hydrophobic by the addition of a surfactant or collector chemical (although some mineral surfaces are naturally …

Shandong 1500t/d Iron Ore Beneficiation Project. Xinhai increased anionic reverse flotation process of magnetic concentrate on the basis of the single magnetic separation process. Iron ore concentrate was obtained directly with a roughing, tailings were discarded with three scavenging, middlings returned to efficient thickener.

Papini et al. (2001) performed a large number of rougher only bench scale flotation experiments of an iron ore from the Iron Quadrangle, Brazil. Different cationic collectors were selected: fatty mono-amine, fatty di-amine, ether mono-amine, ether di-amine, condensate, and kerosene combined with amine.

When it became clear that froth flotation could save the ‘extremely fine free mineral’ in the slime, with a higher recovery than even gravity concentration could make under the most favorable conditions, such as slime-free pulp, froth flotation forged ahead to revolutionize the nonferrous mining industry.
