Magnetic separation of iron precipitate from …
01.07.2015 · This stone proposed a novel process, magnetic seeding and separation, to promote the growth and aggregation of goethite precipitate on the surface of the magnetic seeds, forming a core-shell structure. The magnetic particles will be magnetized and gather together in a magnetic field, accelerating the solid–liquid separation. Combined-analyses were conducted to provide new insights …
Wet High Intensity Magnetic Separation of Iron …
The effect of particle size and magnetic susceptibility on wet high intensity magnetic separation was studied simultaneously. It was found that hematite—1 was a strongly paramagnetic mineral, and the effect of particle size in WHIMS was not significant. Goethite and limonite were weakly paramagnetic minerals, and could not be effectively recovered by WHIMS. The magnetic properties of hematite—2 were between hematite—1 and goethite …
Chemical and mineral transformation of a low …
01.06.2014 · The roasted ore samples were characterized by Wet High Intensity Magnetic Separation (WHIMS) to define the mineral phase transformation of goethite utilizing optical microscopy and point counting. The most important purpose of these analyses was to define the recovery of iron minerals through dehydroxylation and removing impurities via magnetic separation.
magnetic magnetic separation concentrates
Magnetic separation and characterization of vivianite . This suggests that the magnetic separation concentrates the vivianite by a factor 2–3, which is promising at this stage. The magnetic separation also reduces the organic content from 40% to 20% . The remaining could be the organic matter that seems to trap the vivianite crystals, as suggested by Fig. 2 and Frossard et al. . The ...
Evaluation of reduction roasting and magnetic …
01.07.2013 · Two-stage high induced magnetic separations at 16,000 and 11,000 G produces Mn grades with similar grade to that obtained from the ferromanganese feed sample. Reduction roasting followed by magnetic separation on -1.18 + 0.50 mm at 1000 G recovered 72.31% Mn with a grade of 58.44% Mn, 2.52% Fe and 3.29% Si at Mn/Fe ratio of 23.22. This study reveals the influence of roasting in …
