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. Several studies describing the processing of iron ores via reverse cationic flotation are reviewed. The predominate

02/01/2012  Reverse cationic flotation removes quartz using ether amine as a collector, while depressing iron oxide with the use of corn starch in alkaline pulp adjusted by NaOH. In most cases, the pH ranges from 10 to 10.5. In early years, primary fatty amines such as dodecylamine were used in reverse cationic flotation. The fatty amines were of low solubility in pulp and were replaced by more soluble ether
