Bio-Beneficiation of Australian Iron Ores - Potential ...

Iron ore currently mined in Australia generally requires very little beneficiation. However, depleting high-grade resources means that in the future low-grade iron ore deposits will need to be mined to meet the increasing demands of the global steel industry. Along with the increased demand, the industry faces additional pressure to reduce the environmental impact of mining and mineral processing.

Silica and Iron Recovery from a Residue of Iron Ore Flotation

The iron ore concentration tailing in the form that it is generated may have some applications, such as a substitute for sand in cementitious products. De-pending on its purity, the silica may have other applications, such as in the glass industry, ceramics, optics, electronics, etc. [3].

Froth Flotation of Iron Ores

control in iron ore flotation circuits and the level of ionic strength in iron ore flotation pulp. The presence of calcium and magnesium is particularly detrimental to kaolinite removal from iron ore[32]. For dispersant-kaolinite interactions, it was found that sodium silicate, a standard dispersant widely used in iron ore flotation for silicate

Flotation collectors optimized performance

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. As ores become more complex, the
