[10] that the anionic flotation of phosphate ores generally relies on the use of fatty acid surfactant-type collectors, and in the case of high-iron phosphate ores, the depression of iron minerals is usually achieved using starch and the use of this polysaccharide in this

Studies on the Beneficiation of Indian Iron Ore Slimes

The beneficiation potentials of two Indian iron ore slime samples by flotation technique using both cationic and anionic collectors are investigated. The direct and reverse flotation of slimes using oleic acid and dodecylamine as the collector have been studied using both conventional cell and flotation column to upgrade the iron content. The characterisation studies of iron ore

The effects of partially replacing amine collectors by a

The depletion of high-grade iron ore necessitates an upgrade. Froth flotation has been proven to be one of the most suitable separation methods used to this end [3, 5, 6]. The increased use of iron ore flotation has resulted in the reduction of gangue impurities [7]. Flotation has thus produced iron "super-concentrates" with limited

Flotation of Iron Ores: A Review: Mineral Processing and

 · This paper reviews the industrial practices and fundamental research surrounding iron ore flotation. The advantages and disadvantages of direct flotation, cationic reverse flotation, and anionic reverse flotation are reviewed. A novel stepped flotation technique is discussed for the treatment of carbonate-rich iron ores.

pled to 300 g batches for the flotation tests. In this respect, a "Denver D 12" flotation cell was used which is a simulation of the sub-aeration type. Reverse Anionic Flotation of Iron Oxides Contaminants Dodecyl benzene sulphonic acid was used as a collector without or with the addition of rice bran oil as a regulator.

Dry Iron Ore Beneficiation | Iron Ore Separation - ST

Flotation is used to reduce the content of impurities in low-grade iron ores. Iron ores can be concentrated either by direct anionic flotation of iron oxides or reverse cationic flotation of silica, however reverse cationic flotation remains the


 · Now a days, for the beneficiation of major iron ore, froth flotation is popular. For effective flotation, the feed should be finer than 65 mesh. Anionic flotation employing fatty acid or petroleum sulfonate collector is adopted to float out most of the iron oxide minerals leaving behind the gangue, minerals (quartz & clay) in the tailings.
