— 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 ...

 — A dry high-intensity magnetic separator is a waterless separation machine introduced to separate weakly magnetic particles that DLIMS cannot process. This technology employs a greater magnetic field strength provided by an induced or permanent magnet to separate the materials based on their magnetic susceptibility [ 21, 22 ].

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.

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 ...
