Beneficiation of Iron Ore and the treatment of magnetic iron taconites, stage grinding and wet magnetic separation is standard practice. This also applies to iron ores of the non-magnetic type which after a reducing roast are amenable to magnetic separation. All such plants are large tonnage operations treating up to 50,000 tons per day and
The subject of iron ore beneficiation in many kinds of iron ore is magnetite beneficiation. The common magnetite beneficiation processes mainly include a single magnetic separation process and low intensity magnetic separation-reverse flotation process.
Magnetite ore is a significant ore of iron, it is black or brownish-black with a metallic luster, has a Mohs hardness of 5–6 and a black streak. Magnetite ore beneficiation process is divided into crushing, grinding, classification, magnetic separation, dry tailings discharge, three phases.
Polymetallic magnetite – hematite (siderite) iron oreThe iron minerals in this type of ore are mainly magnetite and hematite or siderite, medium to fine grain inlay; gangue minerals are silicate and carbonate minerals or fluorite; Pyrite, chalcopyrite and rare earth minerals.The ore dressing method of such ore is the most complicated in iron ore.

Beneficiation circuits across Brazil typically have Fe ROM grades of 40% as opposed to a global average of 20-30%. This has allowed then to undertake greater size reduction crushing rather than milling to liberate magnetite ore. This results in average milling costs of US$1.8/t.
The magnetic separation process is used as the main method of iron ore beneficiation. The iron ore process is advanced and the utilization rate of magnetite can reach 90%. And the configuration parts cited in the magnetite beneficiation production line are all wear-resistant materials, which can greatly improve the efficiency of the equipment.
To make iron ore size as fine as you can before entering into ball mill, iron ore processors usually are use cone crushers in pre-grinding stage, cone crusher come with an excellent fine crushing power to minish iron ore size. In coarse crushing, 2.1m or 2.2m gyratory crusher is usually being selected, in medium crushing process, processer
The successful development and application of big lump ore dry permanent magnetic separators and high-efficiency magnetic drums (magnetic pulleys) have enabled the beneficiation of low grade magnetite ore to discard 10% to 30% of tailings in advance, and improve the ore into the grinding grade 2-5% has played a great role in reducing the load
Synthesis of magnetite powder from iron ore tailings . 26/07/2010 Abstract Iron ore tailing—a waste material of mineral beneficiation plants, is used as a source of iron for synthesizing magnetite powder Iron ore tailings containing 1598% Fe 2 O 3, 8336% SiO 2 and 044% Al 2 O 3 have been subjected to HCl digestion on a hot plate to extract the entire amount of Fe 2 O 3 as FeCl 3Innovative

The ore dressing method of this type of ore is more complicated in iron ore beneficiation. Generally, the combined process of weak magnetic separation and other methods is adopted, that is, magnetite is recovered by weak magnetic separation; recover weak magnetic materials by gravity selection, flotation or strong magnetic separation.
【Process Introduction】 There are a lot of iron ore in nature, which containes highly quantities of hematite or magnetite.The mainly iron ore beneficiation method is magnetic separation and flotation separation,so the mainly used iron ore equipments are flotation machine, magnetic separatior,efficient thickener,press filter,slurry pump,feeder, agitation tank and belt conveyor etc.

The following are the common iron ore beneficiation technologies summarized by fodamon Engineers: Ⅰ. Magnetic ore. Single magnetite. Most of the iron minerals in single magnetite are magnetite, which has the longest history of mineral processing. Because of the simple composition of ore, weak magnetic separation is often used.

1 Iron ore is sent into the jaw crusher for primary crushing and then sent into the vibrating screen for screening, and the mesh size is controlled in the range of 35 mm to 75 mm. The materials on the screen are sent into the crusher for medium crushing and then sent into the ball mill for grinding.

The principal separation in iron ore beneficiation, therefore, is between the iron minerals, hematite and/or magnetite, and silica, principally in the form of quartz. The use of flotation, either alone or in combination with magnetic separation, has been well established as an efficient method for rejecting silica from these iron ores.
