The former obtains massive rich ore and the latter obtains concentrate by grinding magnetic separation. In order to obtain high-grade concentrate, magnetite concentrate can be treated by reverse flotation or vibrating fine screen. In order to improve the recovery rate, the process of tailings re concentration can be considered for further recovery.
Iron ore processing depend mainly on the type of ROM ore feed and optimum product. Dry screening into lumps and fines is practised for high quality flaky ore and blue dust, because, if wet treatment is used, a substantial part of good quality material is rejected in the form of slimes.

The high-grade iron ore market is largely aligned with iron ore as a commodity in general. In the real world, however, iron units are not fungible commodities - we are increasingly seeing in todays market how ore grade and form can be significant and dynamic factors in value realization.
What is iron ore? Iron ores are rocks and minerals from which metallic iron can be extracted. There are four main types of iron ore deposit massive hematite, which is the most commonly mined, magnetite, titanomagnetite, and pisolitic ironstone. These ores vary in colour from dark grey, bright yellow, or deep purple to rusty red.
Iron ore is smelted after going through beneficiation. 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%.
Then, material must be exposed to moisture reduction processes in order to be stacked and transported to the clients. This processing route is used for the ore that has low iron content. During the dry treatment, no water is added and, after crushing and screening, the ore is ready for the market.
L. Lu, O. Ishiyama, in Iron Ore, 2015. 14.5 Conclusions. Sintering is the most economic and widely used agglomeration process to prepare iron ore fines for blast furnace use. Compared with pellets, production of sinter is cheaper, and compared with lump ore, fluxed sinter is often more reducible with better softening characteristics.

First, moistened concentrates are fed to a rotating drum or an inclined disc, the tumbling action of which produces soft, spherical agglomerates. These green balls are then dried and hardened by firing in air to a temperature in the range of 1,250 to 1,340 C (2,300 to 2,440 F). Finally, they are slowly cooled.
