Ground rules for reducing magnetite losses in DMS plants. While the evolution of dense medium separation (DMS) technology has seen various advances since the mid-1900s, there are still a number of 'fundamentals' that will allow users to reduce magnetite losses over the life of a DMS plant. Speaking shortly after the Southern …

Abstract. This chapter introduces the principle of how low-grade iron ores are upgraded to high-quality iron ore concentrates by magnetic separation. Magnetite is the most magnetic of all the naturally occurring minerals on earth, so low-intensity magnetic separators are used to upgrade magnetite ores. On the other hand, because oxidized …

Materials. Pure quartz (> 99% SiO 2) and magnetite (> 96% Fe 3 O 4) samples (Fig. 1) were obtained from VWR, Sweden.The samples were ground using a laboratory-scale ball mill to produce flotation feed
The curve was calculated for an SPION magnetite core density of 5.24 g/cm 3 and based on data from (Williams et al., 2010; Yamaura et al., 2004). The broken line represents a typical approximation used in magnetic microparticle separation simulations. Note characteristic values of saturation magnetization, M s and the saturation field, H s.
Magnetic separation is a versatile technique used in sample preparation for diagnostic purpose. For such application, an external magnetic field is applied to drive the separation of target entity (e.g. bacteria, viruses, parasites and cancer cells) from a complex raw sample in order to ease the subsequent task(s) for disease diagnosis.
Vanadium titanomagnetite (VTM) is an important mineral for developing titanium resources, but the comprehensive recovery of ilmenite separation is extremely poor, resulting in the low-efficiency utilization of titanium …

The latter property is exploited in the beneficiation of magnetite ores using low-intensity magnetic separation. Although magnetite stoichiometrically contains the highest iron (72.4 wt %) compared with all the other sources of iron, its low-grade ore state usually contains low iron—magnetite ores located in Australia usually contain iron ...
