Mathematical Models to Optimize Magnetic Separator Design. Because alternative processing methods and alternative sources of ore exist, WHIM separation will be commercially applied to oxidized taconites only if it is cost competitive. The key to minimizing costs is to optimize the separator design for a particular application.

Dry permanent magnetic separators have been widely used in the mineral and coal processing industries due to their simple operation and high separation efficiency. These tools not only discard some amount of bulk gangue from the raw ore, thereby reducing the volume of the grinding operation and cutting energy consumption, but also …

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 …

As shown in Figure 13.2, minerals with ferromagnetic properties have high susceptibility at low applied field strengths and can therefore be concentrated in low intensity (<~0.3 T) magnetic separators. For low-intensity drum separators (Figure 13.11) used in the iron ore industry, the standard field, for a separator with ferrite-based magnets, is 0.12 T at a …

The separator is simple in its construction and cheap to build. Its wearing parts consist of the bearings for the shafts, and the cheap, cotton-duck belt, which receives all the wear from the ore, enduring, by reason of its softness, as wax does before the sand blast, the blows which would cut rapidly into a harder and stiffer material.

that broke off and became mixed with the ore. Wet separators are used to separate strongly magnetic material in finely ground mixtures, with the denser water medium holding the small particles apart for individual action by the magnetic field. As most mineral values are found as fine grained crystals that require extensive crushing and fine ...

Magnetic separator is the basic tool used by mineral processing plants to separate ferrous and non-ferrous metals from extracted ore, ensuring high-quality final products. Its works by attracting magnetic particles such as iron, steel and nickel, and then using powerful magnets or electromagnets to separate these particles from other materials.
