The rougher WHIMS stage yielded an iron pre-concentrate (34% Fe) at
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
Iron ore concentration through flotation represents an important application of chemicals in minerals processing. Selective separation between iron oxides and siliceous gangue minerals can only be
Flotation is widely used to concentrate copper, lead, and zinc minerals, which commonly accompany one another in their ores. Many complex ore mixtures formerly of little value have become major sources of certain metals by means of the flotation process. This article was most recently revised and updated by Chelsey Parrott-Sheffer, Research Editor.
The use of flotation for the concentration of iron also involves desliming as floating in the presence of fines results in decreased efficiency and high reagent costs. Desliming is particularly critical for the removal of alumina as the separation of gibbsite from hematite

Descriptions of the use of a flotation process have been found in ancient Greek and Persian literature suggesting its antiquity. During the late 19th century, the process basics were discovered through a slow evolutionary phase. During the first decade of the 20th century, a more rapid investigation of oils, froths, and agitation led to proven work-place applications, especially at Broken Hill, Australia, that brought the technological innovation known as “froth flotation.” During the early 20th century, it dramatically revoluti
The integration of column flotation into existing iron ore plants can be done in a number of different ways depending on metallurgical and economic objectives. Some of the common objectives are: • Incorporate flotation into a plant presently using other concentration methods to permit the production of low silica pellets.
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 century’s practice in the iron ore industry, froth flotation has been established as an efficient method to remove impurities from iron ore.

In the concentration plant, the ore is ground so that impurities can be removed and the iron content raised. The ore is mixed to form a slurry for onward transport to the pelletising plant. The ore is ground in the concentration plant, which means that impurities can be removed
New Steel’s technology can deliver a concentrate with iron content up to 68% Fe from poor ore with content up to 40% Fe, depending on its chemical and mineralogical composition, according to Vale. Currently, this concentrate is produced by flotation, which uses water.
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 most popular flotation route used in the iron industry.

Spiral Spiral concentrator is one of the more common device used for gravity concentration of iron ore. This device is relatively higher in capacity, inexpensive and simple to operate. Generally, the feed enters the spiral channel as homogeneous slurry from the top.
Jan 02, 2012· The flotation routes of iron ore can be classified into five major groups, i.e. cationic flotation of iron oxide, cationic flotation of quartz, anionic flotation of
The Effect of Slurry Concentration on Mining Iron Ore Xinhai. The range of iron ore concentration of reverse flotation is generally 22~40%. Xinhai is a well-known iron ore mining company of flotation cell when mining iron ore and choosing flotation cell, Xinhai is your best choice.Our flotation cell has excellent flotation index, stable production, low energy consumption, wear resistance, low
The froth thickness and this washing process enable a higher enrichment of ore in the froth, improving the quality of concentration and the recovery. The froth that is rich in hydrophobic material is discharged in the launders. In direct flotation, this froth corresponds to the concentrate.
flotation (hematite flotation) or indirect flotation (quartz flotation) tech-niques depending upon the nature of the available ore bodies. In direct flota-tion, iron bearing mineral, mostly hematite, is floated using oleate as collec-tor leaving siliceous gangue, usually quartz, in the tailings. Kick et al. [1]
