Study on Process Mineralogy and Concentrating of a Certain Kyanite Ore in Xingtai

Abstract:

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 -0.074mm 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 a coarse fine two shake, shake in after a rough featured a parted, won the 60.38% grade of Kyanite concentrate and 85% grade quartz ore.
