9.2.2.1. Iron minerals. Based on the magnetic susceptibility values in Table 9.1, iron minerals can be divided into two groups, namely strong magnetic minerals, that is, magnetite (72.4% Fe), and weakly magnetic minerals, that is, martite (70.0% Fe), hematite (70.0% Fe), specularite (70.0% Fe), limonite (57.14–59.89% Fe), and siderite (48.2% …

Operating principle. Slurry is introduced through slots in the upper yoke to the matrix, which is housed inside the vertical separating ring. The magnetic particles are attracted to the matrix and are then carried outside of the magnetic field where they are subsequently flushed to the magnetic concentrate trough.
The process of magnetic separation is based on the differences among magnetic susceptibilities of various mineral species. Performed either wet or dry, the separation has application in both the recovery and concentration of value minerals, and in removing deleterious mineral constituents from a product stream.
High gradient magnetic separation Continuous HGMS (as Sala Maskinfabrik AB, later Sala International AB) has a long tradition in magnetic separation. Already in the end of the 19th century "SALA" built its first electromagnetic separator. The High Gradient Magnetic Separation, HGMS, dates back to early 1970's when "SALA ...

Introduction. Modern high-gradient magnetic separation (HGMS) initially originated from a magnetic filter patented in 1937 by Frantz [1], in which the ferromagnetic matrix of fine wires or rods was first introduced into a uniform magnetic field to increase the magnetic field gradient by several orders of magnitude [2].
