Iron Ore Industry. Most commercial grade iron ore bodies do not require beneficiation to produce a saleable product. Low grade iron ore bodies can be beneficiated using the DEC Flotation column and produce a saleable product at a low production cost per ton.
May 31, 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.
There are several processes developed for the beneficiation of iron ores. In a number of cases, the combination of magnetic separation and silica flotation from magnetic concentrate is practiced.In the treatment of disseminated nonmagnetic iron ore beneficiation, a combination of selective flocculation reverse silica flotation is practiced.
Currently beneficiation of hematite ores is conducted using either direct flotation (hematite flotation) or indirect flotation (quartz flotation) tech- niques depending upon the nature of the available ore bodies.
Although direct anionic flotation was the first flotation route employed in the iron ore industry, it was later largely replaced by the more efficient reverse cationic flotation route. The application of reverse anionic flotation in China in recent years effectively overcomes some flaws of reverse cationic flotation such as high reagent cost and high metal loss …

The iron ore fines (below 150 micron in size) containing silica ( upto 8%) are subjected to physical beneficiation consisting of one more of the following unit operations viz, hydrocycloning, tabling, magnetic separation and flotation of silica to produce a concentrate assaying about 0.3% silica.
beneficiation techniques and advancement in technologies for the upgrading of coarse and fine iron ore utilising dense media separation (DMS), jigging, wet magnetic separation, dry magnetic separation, flotation and x-ray processing.
2017 12 01· 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
In the mining industry or extractive metallurgy, beneficiation is any process that improves (benefits) the economic value of the ore by removing the gangue minerals, which results in a higher grade product (concentrate) and a waste stream ().
The flotation process of the present invention also is unexpected in another direction. It is well known that sulfonated fatty acids such as sulfonated talloel under the flotation conditions described above is a strong promoterfor iron minerals. This process is described in the Booth and Herkenhofi Patent No. 2,417,714.
