1. 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].The steep increase in …

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 …

Deposits of hard kaolin are abundant in China, with kaolin content in the ore exceeding 95%. It is, however, rather difficult to remove iron from the ore. It was demonstrated that wet high–gradient magnetic separation is very efficient in removing the iron compounds from kaolin. For hard kaolin, however, dry high–gradient magnetic separation …
