— Magnetic separation equipment is widely used in the separation of magnetic minerals. Low-intensity magnetic separator is mainly used for the separation of minerals with specific magnetic susceptibility greater than 1 × 10 −6 m 3 /kg, such as magnetite, vanadium titano-magnetite, pyrrhotite, and other minerals. Medium-intensity magnetic …

Dry low intensity magnetic separation dry drum separators have been developed mainly for dry separation of ferromagnetic ores with particle sizes finer than 20 mm. In addition to this conventional application, the dry drum separator has found a wide range of other applications such as: • Iron and steel slag treatment • Reduced pyrite ...
The relevance of the paper is that dry magnetic separation (DMS) is the main beneficiation method of magnetite ores. The lack of efficient industrial-grade machines and apparatus for separating fine-grained magnetite ores means that DMS is used mainly as a pre-concentration operation for fairly large classes.

Dry high-intensity magnetic separators (induced roll magnetic separators and permanent roll magnetic separators) are an outcome of the experience gained by the working engineers and scientists over the years in the plant, essentially designed to utilize high intensity magnetic field for the separation of Paramagnetic particles.
— Magnetic separation performs poorly with non-magnetic or only weakly magnetic materials like gold and graphite. Using it as the sole method won't effectively process these ores. Thus, magnetic separation applications remain constrained regarding suitable ore bodies. Most mineral separations still require gravity, froth flotation, or other ...
Magnetic separation theory The magnetic separation of magnetite and other magnetic minerals is a complex process. During the separation process, each particle is subjected to a number of forces, including grav-ity, drag, etc. The simplified equation below describes the magnetic force the particles are subjected to: Magnetic force:
Sepor can provide dry separators with low, medium and high intensity magnetic fields. The low intensity drum has a magnetic field from 600 to 1,000 gauss, while the medium and high intensity drums have magnetic field intensities ranging from 3,000 gauss (Rare Earth Magnetic Drum) to 20,000 gauss (Electro-magnetic drums). We have a full range of ...
