    Experimental study on performance of a continuous

    Apr 30, 2008 However, the magnetic force has its significant effect on the overall behavior of the magnetic particles in a HGMS separator. HGMS can be used to preconcentrate weakly magnetic minerals, but generally it cannot be used to produce a high grade marketable concentrate (Xiong, 1997, Zeng and Xiong, 2003).Fote Mining Machinery Co. When HGMS is used to concentrate hematite ... read more

  • Pulsating high gradient magnetic separation of fine

    Pulsating high gradient magnetic separation of fine

    Aug 01, 2009 Pulsating high-gradient magnetic separation (PHGMS) of fine hematite from tailings was studied using a pilot PHGMS separator to investigate the possibility of its application in industry. The results of this investigation indicate that PHGMS is effective for recovering fine hematite from the tailings and greatly improved the separation performance compared with the conventional high-gradient ... read more

    cation of magnetic separation in non-ferrous material has been reported by Geldenhuis to recover nickel from flue dust using wet low intensity magnetic separator.5) The last two studies above show that nickel and iron can be easily recovered by using low intensity magnetic separator, indi-cating that both elements have high magnetic properties. read more

  • Difference Between Magnetite and Hematite Definition

    Difference Between Magnetite and Hematite Definition

    Jan 31, 2018 Magnetite and hematite can be separated from each other using their magnetic properties. Magnetite is ferromagnetic and hematite is paramagnetic. Therefore, these substances can be separated using low-intensity magnetic separation method. Here, an induced roll magnetic separator with a magnetic field with a 0.04 Tesla intensity is used. read more

    Feb 05, 2021 The lowest magnetic susceptibility mineral which is separable on conventional dry-type magnetic separators is represented by monazite. Estimated susceptibility from separator response is approximately 12 x 10 -6 emu. A number of compounds of lower magnetic susceptibility have been selected here to demonstrate the lower limits of the separator. read more
