2.4 High-Gradient Magnetic Separator (HGMS) As its name implies, a high gradient magnetic separator employs magnetic field charges to separate magnetic materials. Marston and Kolm introduced this method at the Massachusetts Institute of Technology in the late 1960s and early 1970s.
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.
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.
Magnetic separation plays a crucial role in the extraction and processing of minerals. It is employed for the concentration of magnetic ores, the removal of impurities from valuable minerals, and the recovery of magnetic materials from waste streams generated during mining operations. Magnetic separation is extensively used in recycling ...
