The raw materials for direct magnetic concentration are poor iron ores (mainly magnetite) and minerals of manganese, titanium (containing ilmenite and titano magnetite), and tungsten (wolframite); in the process, valuable minerals are separated into the magnetic fraction (magnetic concentrate).

Magnetite is a rock mineral and one of the main iron ores, with the chemical formula Fe3O4. It is one of the oxides of iron, and is ferrimagnetic; it is attracted to a magnet and can be magnetized to become a permanent magnet itself. It is the most magnetic of all the naturally occurring minerals on Earth. Naturally magnetized pieces of magnetite, called lodestone, will attract small pieces of iron, which is

Magnetic Concentration. In dry magnetic concentration, the ore is loaded onto the upper drums of a magnetic separator, which contain open permanent magnets that generate a field with an intensity of about 90 kiloamperes per meter (kA/m) on the surface of the drum. The magnetite ore is attracted to the poles (the surface of the drum),

The amine flotation of feldspar from magnetite concentrate was investigated using zeta potential measurements, Hallimond tube flotation tests and laboratory scale flotation tests. The zeta potential of various feldspars (microcline, albite, anorthite, oligoclase and anorthoclase) were determined as a function of pH; the point of zero charge ranged from pH 1.4 to 2.5.

Its iron content should be greater than 82% while silicon is in the range of 15 16%. If ferrosilicon contains more than 16% Si in it, its magnetic susceptibility will decrease and its regeneration with magnetic separation will become difficult, less than 15% silicon will cause corrosion of ferrosilicon alloys.
 Environmental problems linked to the concentration of atmospheric particulate matter with dimensions less than 10 m (PM 10) in urban settings have stimulated a variety of scientific researches.This study reports a systematic analysis of the magnetic properties of PM 10 samples collected by six automatic stations installed for air quality monitoring through the Latium Region (Italy).
Subsequently, the concentrates can be purified by magnetic concentration using a weaker magnetic field and the mixed particles can be ground and concentrated by inverse flotation . Another alternative is to blend the concentrates with rich by products (with content of Fe, SiO 2 , Al 2 O 3 , P, etc.) the qualities required for steel making.
9.4.2 Typical separation flow sheets for magnetite ores. Magnetite is strongly magnetic, so low intensity magnetic drum separators (drum LIMS) are widely used in processing magnetite ores. But in the final stage of separation, because the selectivity of magnetic columns or reverse flotation is better than that of drum LIMS separators, these separation technologies may be used to obtain a better

The specific gravity is maintained at 1.30 in the heavy medium cyclone. The cyclone overflow is a clean coal product containing part of the magnetite medium, and the underflow is refuse and middlings also containing part of the medium. Both of these streams are pumped to
The magnetic properties indicate that the PM is composed of fine grained PSD magnetite, but since the SP fraction could not be analysed their impact in the magnetic signature was uncertain. The bipartition of magnetic particles between traffic light crossings and midway areas was less obvious than expected, but this might be due to the high

A DISCUSSION OF MAGNETIC SEPARATION TECHNIQUES 201 Low intensity magnetic separators are utilized to recover any remaining magnetite. The LIMS is followed by a rougher stage of two SLon 1500 magnetic separators. A third SLon 1500 magnetic separator is then applied to recover ilmenite in a cleaning stage.
A new mobile iron ore washing plant for Bhushan Power Steel is delivering a substantial in Fe through the effective removal of alumina and silica from the feed material.
