Impurity Removal in the Reverse Flotation of Iron Ore

Vale is the largest iron ore producer in the world. Since the 1970s, Vale has been using reverse cationic flotation to remove siliceous impurities from its iron ores. Whilst this flotation process has operated effectively for many years, it suffers from the problems of high reagent costs and high metal loss.In 2010, CSIRO investigated the use of a reverse anionic flotation process for

An overview of the beneficiation of iron ores via reverse

The main routes of iron ore flotation were reviewed. • 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 Fe-bearing silicates deserve further investigations. Abstract. Flotation is the most effective solution, both technologically

Froth Flotation of Iron Ores article.sapub

02/01/2012 Although the reverse cationic flotation route has become the most popular flotation route in iron ore industry, the direct flotation of iron oxides still appears desirable for some low grade iron ores that contain a vast amount of quartz. For example, at Republic Mine, Michigan, U.S.A., a hematite ore is upgraded from 36.5% Fe to 65.4% Fe with a Fe recovery

Optimal Control of Iron Ore Flotation with Soft Sensors

23/10/2015 For Brazilian iron ore producers, reverse cationic flotation is preferred to obtain high quality concentrates from silicate ores. The SiO2 (silica) particles are rendered hydrophobic by amine (cationic collector) in alkaline conditions, while iron is depressed by the addition of starch. The injected air forms bubbles to which the silica attaches due to the amine action,
