reverse froth flotation for iron ore
An overview of the beneficiation of iron ores via reverse
Reverse cationic flotation is the most used flotation method of iron ore beneficiation. Ether amines and starches are usually used as collectors and depressant, respectively. Selective depressants for Febearing silicates deserve further investigations.

Froth Flotation of Iron Ores
The practice of froth washing in direct flotation increases concentrate grades without significant recovery losses[59]. In the reverse flotation of iron ores, froth washing was found effective in reducing the loss of FINE iron oxide particles to froth.

Production of High Grade Iron Ore Concentrates Using Flota
Abstract For many iron ore producers selling pellets in the h ighly competitive international market place, the ability to produce high quality products at low cost has become vitally important. A strong demand for low acid pellets suitable for direct reduction has resulted in an increase in the number of plants util ising reverse froth flotation for silica reduction.
