Direct flotation of iron ore using oleic acid is relatively expensive in terms of high reagent consumption and entrapment of gan-gue minerals in the froth. Therefore. beneficiation of iron ore fines by reverse flotation using cationic collectors is gaining wider application in
COLUMN FLOTATION FOR THE BENEFICIATION OF IRON ORE FINES. Beneficiation studies using various techniques such as washing, jigging, hydrocyclone, spiral, advanced gravity separations, magnetic separation, flotation etc. were carried out to develop a suitable process flowsheet as a step towards the upgradation of iron values and to reduce gangue content.
Flotation, on the other hand, is used to reduce the content of impurities in low-grade iron ores 1-2,5. 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 most popular flotation route used in the iron industry 5,7.

Jan 02, 2012 With the depleting reserves of high-grade iron ore in the world, froth flotation has become increasingly important to process intermediate- and low-grade iron ore in an attempt to meet the rapidly growing demand on the international market. In over half a centurys practice in the iron ore industry, froth flotation has been established as an efficient method to remove impurities from iron ore.
Samples from an orebody containing wollastonite approximately 69 percent, with quartz, calcite, and iron-bearing minerals as the main impurities, were investigated for possible beneficiation. This involved attempts to reduce the iron content by magnetic separation and to remove the quartz and calcite by flotation.
Flotation was discovered early in the 20th century, and today it is the most commonly used separation technology in the mining industry. Flotation separates valuable minerals copper, lead, zinc, iron, and phosphate too from the contaminating minerals in the ore sand in this case.

Froth Flotation Beneficiation process is one of the important processes in the application of ore dressing, and it is widely used. Froth Flotation Beneficiation is widely used in copper, nickel ore, iron ore, gold ore, lead and zinc ore, potassium feldspar, graphite and other metal and non-metal ore concentrate selection, with high efficiency, low energy, high handling capacity, reasonable ...
Iron ore is beneficiated using separation steps based on mineral composition without the use of separation steps based entirely on size. In a preferred sequence of steps the iron ore is passed from a ball mill through a magnetic separator where low iron content tailings are rejected and the concentrate passed to a flotation step, where a high iron content concentrate froth is made and the ...
Dry processing of iron ore presents an opportunity to eliminate costs and wet tailings generation associated with flotation and wet magnetic separation circuits. STET has evaluated several iron ore tailings and run of mine ore samples at bench scale pre-feasibility scale. Significant movement of iron and silicates was observed, with examples ...

Iron ore mining often focuses on looking for hematite deposits known as red iron ore, and magnetite, as they have naturally weak magnetic fields that aid in their purification. Hematite, however, responds better to the flotation process in iron ore beneficiation than magnetite, so it is the preferred type of ore.
