Maximizing the recovery of fine iron ore using magnetic separation Most iron ore operations that require beneficiation of ROM ore to produce lump, fine (sinter), and pelletizing concentrate iron ore products will discard a slimes fraction to final tailings. This fraction can vary in particle size from –200 µm down to –10 µm.

Dry iron ore beneficiation is without doubt currently being driven forward by Vale in Brazil. The company wants to increase its capacity from 340 Mta iron ore at present to 450 Mta in future, dry beneficiation is to be further increased by 10 % from 60 % at present. Dry beneficiation capacity will increase by around 110 Mta.
Magnetic separator separates the iron ore feed material into two or more components. If the purpose is to produce a magnetic concentrated iron ore then the other component which is non-magnetic is the tailings. In some cases there can also be a possibility of separating the less magnetic third component which is called middlings. Each of these ...

Vale has filed a patent for a system designed to remove iron ore particles from a vertical magnetic separator using a magnetic matrix. The system includes features such as an ore feed inlet, an accumulation vessel, collecting trays, a demagnetizer, a cleaning device, and compressed air jets for efficient operation.
Several attempts have been made by different researchers and technologists to understand the separation behavior of particles in each of these separators treating different types of para-magnetic minerals. Despite all these efforts, these separators are yet to find widespread applications to treat different para-magnetic minerals.
During the magnetic separation process, materials are classified into paramagnetic and diamagnetic depending on whether or not the effect of magnetic field on them are strong or not respectively. The capacity of a magnetic separator to lift a particular mineral is dependent not only on the value of the field intensity, but also on the
This chapter introduces the principle of how low-grade iron ores are upgraded to high quality iron ore concentrates by magnetic separation. Magnetite is the most magnetic of all the naturally occurring minerals on earth and can be readily extracted by low-intensity magnetic separators from magnetite ores. On the other hand, oxidized iron ores ...
Magnetic separation enables selective separation based on the magnetic properties of materials, allowing for precise separation of target substances from complex mixtures. Magnetic separation is a nondestructive technique that does not alter the chemical or physical properties of the separated materials, making it suitable for sensitive ...
Goal: Demonstrate and commercialize a 100 ton-per-hour magnetic elutriation device for the domestic iron ore industry. Magnetic elutriation improves the quality of low-grade domestic …
Iron titaniferous sands, also called black sands, are a source of various magnetic minerals, such as iron and titanium (Fe–Ti) oxides, with countless scientific and industrial applications. Ecuador is deemed a geo-diverse country that contains deposits of black sands in the Andean and coastal regions; therefore, the industrialization of these magnetic sands …
The separation matrix material behaves like a magnet and selectively attracts the magnetic fines while the non-magnetic particles fall through the matrix slots and into the non-magnetic launder. The ring is rinsed when it is out of the magnetic field and all the magnetic particles report to the magnetic launder.
Magnetic separation is often considered pertinent for manganese ore beneficiation when the ore is abundant with siliceous rich gangue mineral phases. However, the process is deemed to be inapposite for the ferruginous type of ore, and remains a grey area of research. In the present investigation, two different types of manganese ore were studied in …
Our two-stage magnetic separator therefore combines a STEINERT MTP extracting magnetic drum with a STEINERT MSB traversing magnetic pulley. Whilst the former generates valuable scrap iron, the magnetic pulley in the second stage separates weakly magnetic components that represent impurities in downstream processes and can have a negative impact ...
Utilizing magnetic separation is an important step towards achieving green and low-carbon steel production. In China, every 1% increase in iron ore concentrate grade increases blast furnace utilization factor by 2% to 3%, coke consumption by 1.5%, and limestone consumption by 2% [34].
In this paper, a sample from Tange-zagh iron mine was characterized by gravity and magnetic separation methods. The mineralogical studies showed that hematite and goethite are the main iron-bearing minerals with insignificant amounts of FeO. The results indicated that spiral separation yields higher separation efficiency than others. The combination of spiral …
This chapter introduces the principle of how low-grade iron ores are upgraded to high-quality iron ore concentrates by magnetic separation. Magnetite is the most magnetic of all the naturally occurring minerals on earth, so low-intensity magnetic separators are used to upgrade magnetite ores.

The removal of "tramp" iron from feed belts can also be regarded as a form of low-intensity magnetic separation. However, tramp iron removal is usually accomplished by means of a magnetic pulley at the end of an ore conveyor (Figure 13.12) or by a guard magnet suspended over the conveyor belt (see Chapter 2).Tramp iron removal is important prior to crushing and …
