The problem is to utilize millions of tons, and we may safely say billions of tons, of now worthless iron-bearing rock and to produce from it 10,000,000 to 20,000,000 tons per year of high-grade ore carrying 60 per cent, iron or higher; to take the lean material as found in nature, varying widely in iron content, and bring it up to a uniform ...
Dwari et al. (2013) used a combination of dry and wet magnetic separation methods to upgrade a low-grade siliceous iron ore with magnetite, hematite, and goethite as major iron minerals. The study showed that for particles finer than 200 µm, the separation methods produced a magnetic concentrate with 67% iron and iron …
b. Magnetic Separation: Magnetic separation utilizes the magnetic properties of iron ore minerals. High-intensity magnetic separators are used to separate the magnetic iron-bearing minerals from the non-magnetic gangue minerals. This technique is effective for removing strongly magnetic impurities from the ore.

Different materials possess different magnetic properties by which they may be separated. Figure 9.1a shows that when a magnet is placed close to an iron ball and a ceramic ball, the iron ball will be attracted to the magnet and the ceramic ball will not. Figure 9.1b shows that when a magnet placed close to a group of mixed tiny iron and …
The cost of a Iron Ore Magnetic Separator can vary widely depending on its size, capabilities, and complexity. Most of the price of Iron Ore Magnetic Separator ranges from US $ 1000 to $ 400000 per Piece.

According to statistics, the annual emission of iron ore tailings is 130 million tons, while every 1 ton of iron ore concentrate should discharge 2.5–3 tons iron ore tailings. Assuming the tailings contain an average of 11% iron, there are 1.41 million tons of metallic iron losses in the tailings [11] .
