·The major impurity in Brazilian iron ores is quartz and the preferred strategy for this type of iron ore is reverse cationic flotation of quartz as the other two strategies lead to poorer concentrate grade due to entrainment The advent of reverse flotation for iron ore took place in the 1940s to process iron ores in the Great Lakes region
·Four types of cationic collectors were tested and evaluated for their performance in the reverse flotation of silica from the spiral preconcentrate of Kudremukh iron ore A stagewise flotation was conducted by adding the reagent in three stages Starch was used to depress hematite Silica flotation was found to be very sensitive to the amount of cationic reagent added
·Flotation is the most effective solution both technologically and economically when upgrading iron concentrates 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
·Removal of quartz from iron ore was accomplished industrially via an anionic reverse flotation technique However in that kind of flotation the interaction of the flotation reagents with the
