In this paper, the mineral properties of the lean magnetite in RongTian mine corporation was studied, during which the analysis of the mineral properties, prelimenary separation on the lump mine, two-section grinding, one section fine screening and three-section low intensity magnetic separation process were carried out. The results showed that if the suitable mineral processing flowsheet is adapted, we can achieved such index:concentrate grade of 63.65%, Fe recovery of 47.12% based on the ore grade of 10.05%.. According to the experimental result analysis, most of the iron minerals could be used to support the steel production of LingGang Group.Single magnetic process proved to be an suitable and promising process to conduct the fine particles of lean magnitite.

Specific Speed

A passive control of an unstable characteristics of a high specific speed diagonal-flow fan has been proposed. It is possible to eliminate the unstable characteristics of pressure-flow rate curve in a low flow region without deterioration of performance at design point. The control action is done naturally (passively) without any energy input. The inlet nozzle of an ordinary diagonal-flow fan was replaced by an annular wing with Göttingen 625 airfoil section. The mechanism of the passive control and the optimum geometrical parameter are discussed on the basis of the performance tests and internal flow measurements.

In this paper, the method of “floatation—microwave magnetic roasting—low intensity magnetic separation” which aims to utilize the iron and Nb mineral in the Bayan Obo tailings was investigated. The results show that the method of “floatation—microwave magnetic roasting—magnetic separation” is effective and simple, and the recovery of iron and Nb in the whole process is up to 80% and 68% respectively. The step of microwave magnetic roasting is researched carefully, and the best magnetic roasting result is obtained at 650°C, and the roasting time is 10min.The best result of magnetic separation is obtained at the magnetic intensity of 220KA/m. Iron ore concentrate separated by magnetic separation can be used for iron making directly because the grade can reach about 62~64.4%. And the grade of Nb can reach up to 2.16%.

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%.

A survey of magnetic separation research at FDO Engineering consultants, the University of Nijmegen, and the Energy Research Foundation (ECN) will be given.FDO efforts were primarily on coal cleaning using the high gradient magnetic separation (HGMS) technique. The Institute for Materials of the University of Nijmegen performs fundamental studies on magnetic flocculation. A continuous flow magnetic separator is briefly described. The Energy Research Foundation has built and operates an HGMS–system with superconducting magnets. Auxiliary equipment enables the execution of well controlled HGMS pilot scale tests.Intensive contacts and cooperation exist between scientists of the 3 research organisations, and with other industries which are interested in magnetic separation applications.
