An overview of the beneficiation of iron ores via reverse

Despite the recent success of the reverse anionic flotation of iron ores in the Anshan province in China, reverse cationic flotation remains the most popular flotation route used in the iron ore industry ().Comparing reverse anionic and cationic flotation is difficult because the processes are governed by the chemical, physical and metallurgical properties of the iron ores.

An overview of the beneficiation of iron ores via reverse

Research regarding iron ore flotation began in 1931, demonstrating that reverse cationic flotation is a very efficient method for beneficiating oxidised iron ores. This method can also be applied to reduce the silica content in magnetite concentrates obtained using wet low-intensity magnetic separation.

flotation of low grade iron ore

Beneficiation of a low-grade iron ore was investigated by combination of the low-intensity magnetic separation and reverse flotation methods. The main constituents of the representative sample were 36.86% Fe, 8.1% FeO, 14.2% CaO, 13.6% SiO2, and 0.12% S based on the X-ray fluorescence, titration, and Leco analysis methods.
