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

Flotation collectors optimized performance

Flotation of phosphate Phosphate ore is the most important source of phosphorus in fertilizers. To supply the phosphoric acid plant with phosphate, a high grade of phosphorus is essential, as well as reduced levels of impurities such as magnesium, iron and aluminum oxides. Flotation is one of the key beneficiation methods.
