In this investigation, a full-scale cDMS1000 separator was used to evaluate the cDMS performance for fine magnetite ore. As shown in Fig. 1, the cDMS1000 separator is mainly composed of feeder, driving mechanism, separation cone, dust hood, receiving funnels and support frame.In the separator, a permanent magnet system was adopted, and it operates in a …
the benefit of being easily recoverable by magnetic separation. Ferrosilicon has a higher specific density (6.8 g/cm 3) than magnetite (4.5 g/cm ) and can therefore produce a higher range of relative medium densities. However, ferrosilicon is more expensive and finds use primarily when the higher separation densities are required.
Magnetic separators are commonly used to separate magnetite iron ore. They directly separate magnetite sand or sea iron sand. For rocky magnetite, crushing and grinding is required first before magnetic separation. Magnetic separators consist of a drum where magnets are embedded to attract magnetic materials from non-magnetic tailings.
Concentrators, which are used for the separation of magnetic ores from the accompanying mineral matter. These may operate with dry or wet feeds and an example of the latter is the Mastermag wet drum separator, the principle of operation of which is shown in Figure 1.43.An industrial machine is shown in operation in Figure 1.44.A slurry containing the magnetic …
An important role is being played by projects for iron ore concentrate extraction by means of dry magnetic separation (Fig. 16). Three projects with a total of 9.6 Mta are already in the construction phase, another project with 8.5 Mta capacity concerns the production of iron ore pellets.
Magnetic separation equipment has long been used to upgrade and beneficiate a wide variety of minerals and materials. Over the years, significant advances in both wet and dry magnetic separators have improved their operability and separation performances, broadening their use. However, certain areas of weakness still remain, including: fine particle processing, high …

Conventional magnetic separation is to separate minerals according to their natural magnetism. In addition, in some cases, in order to improve the efficiency of separation, it is possible to change the magnetism of minerals or take some special methods to make the mineral separation more effective, such as magnetization roasting and magnetic separation, magnetic …
MAGNETIC SEPARATION N. Chakravorty le Introduction: Magnetic separation employs the difference in magnetic properties of minerals to effect separation between them. The magnetic separation may be for removing ore particles which are magnetic or conversely to remove magnetic impurities from a product which is non-magnetic.
