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.
Froth flotation is considered to be the most widely used method for ore beneficiation. In ore beneficiation, flotation is a process in which valuable minerals are separated from worthless material or other valuable minerals by inducing them to gather in and on the surface of a froth layer.

Deposits of comparatively lower grade iron ore that remain relatively untouched or by-passed, are now most important because of increase in consumer demands. Deposits of comparatively low grade specular hematite amenable to beneficiation by flotation have produced concentrates superior …
The Iron Ore Process Flowsheet. The iron ore beneficiation flowsheet presented is typical of the large tonnage magnetic taconite operations. Multi-parallel circuits are necessary, but for purposes of illustration and description a single circuit is shown and described.
flotation cells. CPT Inc. has developed a flotation process for the production of Direct Reduction (DR) as well as Blast Furnace (BF) grade concentrates utilising column flotation technology. This process has been adopted by several major iron ore producers and current aggregate production is approximately 50 MTPY of DR grade concentrates.
Xinhai increased anionic reverse flotation process of magnetic concentrate on the basis of the single magnetic separation process. Iron ore concentrate was obtained directly with a roughing, tailings were discarded with three scavenging, middlings returned to efficient thickener.
Froth flotation is a process for separating minerals from gangue by taking advantage of differences in their hydrophobicity.Hydrophobicity differences between valuable minerals and waste gangue are increased through the use of surfactants and wetting agents.
Froth flotation is a highly versatile method for physically separating particles based on differences in the ability of air bubbles to selectively adhere to specific mineral surfaces in a mineral/water slurry.

The flotation method of concentration, used extensively for other metal ores, has only recently been utilized for hematite iron ores. It can be applied as either the sole concentration process or as a final concentration stage to ensure a high-grade product. In the flotation process, air is bubbled through a suspension of fine iron ore in water
Nov 05, 2018· 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.
