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% Fe).While magnetite ores are naturally …
Currently, industrial magnetite beneficiation is carried out as a wet process (Karmazin et al., 2002).The most common technology used for magnetite beneficiation is wet drum low-intensity magnetic separators (WLIMS) (Xiong et al., 2015, Dworzanowski, 2010).Conventional WLIMS flowsheets for magnetite beneficiation include multiple stages of …
Applying various composite force fields can bring about improvements, including combining magnetic field with vibration force [3,4,5], centrifugal force [6,7,8], gravity [9,10,11,12,13,14] and fluid force [15,16,17]. It is worth noting that almost all composite force terms essentially strengthen the fluid force on particles.
