When the dosage of the Lilaflot collector increase to 30-50g/t, the iron grade of the iron concentrate is up to 69.90%, the silica 2.80%, which is suitable for a direct reduction of iron concentrate. The sulfur content of the concentrate is an important indicator for the concentrate quality after magnetite reverse flotation.
In iron ore direct flotation process, a sort of direct flotation reagent is added and then works under specific conditions. The floating material is mainly iron concentrate. On the contrary, iron ore reverse flotation uses reverse flotation regents to work under given conditions, and its floating material is mainly gangue mineral.

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.
In reverse flotation of iron ore, the silicate gangue minerals (primarily quartz) are recovered into the froth phase using cationic collectors such as amines at a pH of approximately 9 to 11. Because the concentrate in this case is the material that does not float, while the froth is the tail-
hence reverse flotation can be employed rather than direct flotation wherein major proportion of the material,otherwise, would have to be floated. As such,the reverse flotation is the usual process for the beneficiation of iron ore slimes. Amines are the only cationic collectors used by industries in reverse flotation of iron ores.
Reverse cationic flotation is currently the most widely used flotation route in the iron ore industry. The metal loss at the de-sliming stage, which is essential in reverse cationic flotation, and the high cost of amine collectors are the common issues/problems of reverse cationic flotation.
