2017-2-1 To improve the efficiency of iron recovery from steel slag and reduce the wear-and-tear on facilities, a new method was proposed by adding a secondary screen sizer to the magnetic separation process according to grain size distribution of magnetic iron (M-Fe) in the slag.
magnetic separation.9–11)This technology combines metal- lurgy and mineral processing, in which iron oxides are primarily reduced to metallic iron with grain growth.
2009-8-26 Low-intensity magnetic separators are utilized to recoverany remaining magnetite. The LIMS is followed by arougher stage of two SLon®-1500 magnetic separators. Athird SLon®-1500 magnetic separator is then applied torecover ilmenite in a cleaning stage.

This slag was grinded in iron mortar to 3 classes of particle size: 32mm, 53mm, and coarse (10–300mm), to be used in a magnetic separation experiment. 2.3. Magnetic Separation Experiment A schematic diagram of the apparatus used in the mag-netic separation experiment is shown in Fig. 3. 0.14g crashed slag was added in a Pyrex cell (f16.5mm

2016-5-24 Beneficiation of Iron Ore and the treatment of magnetic iron taconites, stage grinding and wet magnetic separation is standard practice.This also applies to iron ores of the non-magnetic type which after a reducing roast are amenable to magnetic separation
A magnetite concentrate containing 68.75% Fe was produced from Sample A at an iron recovery of 97.23% through the multiple-stage wet frictional grinding-magnetic separation flowsheet.
The refractory iron ore treated by the present method can be produced to homogeneous magnetite or maghemite accurately, and through magnetic separation, on-line grade analyzer detection and ore-like splitter, the concentrate powder which reach the set grade can be obtained, and the unqualified ore powder enters the next stage of oxidation
2021-4-29 magnetic separation is sufficient iron grain size to release gangue from the metallic part during grinding. Therefore, the physicochemical conditions of the metallization process should provide not only full reduction of iron oxides, but also a certain size of metallic particles above a certain limit.
It is found that the presence of 12% sodium sulphate during reductive roasting significantly improves separation of iron and aluminium in magnetic separation: the total iron grade (TFe) of
In the primary stage of quartz sand purification, wet magnetic separation is generally considered to be an excellent way of iron removal purification, but in the stage of high-purity quartz cleaning, the conventional wet magnetic separation purification effect is not obvious, the reasons can be summarized as three points. 2606-2021
2021-4-1 Microwave reduction roasting and magnetic separation could efficiently recover metal iron from red mud. Chen, et al., 2011: Microwave reduction roasting and magnetic separation could efficiently utilize limonite with lignite as reducing agent. Wang, 2011
As a result of dry magnetic separation at about 750 Gauss magnetic field conducted with -0.212+0.106 mm size fraction under optimum conditions, a magnetite concentrate assaying 54.41% Fe was

Magnetic separation: one-stage roughing and three-stage concentration. (Xinhai rubber pump was used to transport slurry.) Concentrates and tailings transportation: iron concentrates were dehydrated in the permanent magnetic filter and then transported by belt conveyor to the iron concentrates powder dump, and tailings flowed by gravity to the
An integrated value chain for magnetic separation, microwaves digestion and microemuslsion-assisted extraction, concentration and recover of some metals from iron-containing mine tailings and the corresponding physical-chemical techniques applied for the investigation are proposed in the Scheme 1.
