Froth Flotation of Iron Ores - sapub

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.

Removal of gangue components from low-grade iron ore by ...

Based on these results, we determined that hydrothermal treatment is an effective method for upgrading low-grade iron ore because of the possibility of transformation of the goethite in the iron ore into hematite with low porosity, thereby lowering gangue content. Thus, this method can produce high-grade iron ore from low-grade iron ore.
