Depending on whether an ore is sulfide or oxide, the process follows one of two routes. Beneficiation Beneficiation is the concentration of ore through separation into desirable mineral the part of the ore that is useable; and gangue (pronounced gang) the part of the ore that is commercially worthless.

Abstract Beneficiation of high alumina iron ore fines from Noamundi, India is studied for producing sinter/ pellet grade concentrate. The iron ore fine sample has a feed grade of 59.77%Fe, %4.71SiO 2, and % 5.89Al 2 O 3 with % 5.53 of LOI (Loss on Ignition).
The main routes of iron ore flotation were reviewed. Reverse cationic flotation is the most used flotation method of iron ore beneficiation. Ether amines and starches are usually used as collectors and depressant, respectively. Selective depressants for Fe bearing silicates deserve further investigations.

substantial expansion of iron ore pellet plants or iron ore beneficiation plants from 7.5% to 2.5%. This will lead to a rise in iron ore mining. Similarly, growth in the production of zinc, lead, bauxite and other minerals is also expected, catalysing the demand for explosives. The Indian steel sector will add 23 MT capacity largely through
The iron ore industry classifies the material by the concentration of the metal that is present after iron ore beneficiation has been completed. High grade iron ore must have a concentration of 65% iron or higher, and medium grade of 62% to 65%.
1. Iron ore supply and demand outline 1.1 Types of iron ore Iron ores can be classified in different ways. The most important has to do with the iron content. In many cases, ore with a total iron content of 60% to 63%, or greater, is regarded as high grade, and ore with a lower iron content is regarded as low grade.
The Lower grade sources of iron ore generally require beneficiation, using techniques like crushing, milling, gravity or heavy media separation, screening, and silica froth flotation to improve the concentration of the ore and remove impurities.
