Recovery of high grade iron compounds from LD slag by enhanced magnetic separation techniques

As high-grade refractories raw material，kyanite is widely used and the market demand is increasingly greater. To identify the process mineralogical properties of kyanite from Heibei so as to provide a mineralogical basis for its chemical composition, mineral constituent，ores texture and structure and so on. The results show that: the kyanite Al2O3 21.50%, SiO2 52.87%, using high intensity magnetic separation-gravity separation-flotation folwsheet. Experiments show that, the grinding fineness of -200 mush 65%, with strong intensity magnetic separation, magnetic concentrate by shaking the low intensity magnetic separation，we can get magnetite, garnet, biotite and phlogopite four concentrates, strong magnetic ore tailings consolidated by a rocking bed mud thrown first, refined through flotation, won Kyanite concentrate grading about 56.11% at a recovery of 49.90%.

The Magnetic Field

Laboratory research on the mineral processing technique of a specularite ore from Baxi was performed, while the processes including gravity separation, low intensity magnetic separation(LIMS) -high intensity magnetic separation(HIMS)-gravity separation was adopted. The run-of-mine ore was milled till the -0.074 mm range accounts for 50% and treated through a LIMS – HIMS process, with the magnetic field strength of LIMS being 95.52 kA/m and HIMS,1.2T. As a result, an iron concentrate grading about 67.58% at a recovery of 96.21% can be obtained, which are rather good metallurgical performances. The iron concentrate with high grade also could be beneficiated by table separation, but its recovery is lower than it obtained from intensive LIMS – HIMS dressing.
