Effect of microwave heating on magnetic separation of pyrite

Sep 15, 2003· The microwave treated pyrite samples of −420 μm fraction were subjected to magnetic separation at magnetic field intensities of 0.1, 0.3 and 0.5 T. It was found that pyrite was converted to such ferromagnetic minerals as pyrothite and γ-hematite, and magnetic separation recovery was improved after microwave treatment.

Enhanced magnetic separation of pyrite from coal after

Abstract: The objective of this research was to improve the magnetic separation of coal and pyrite by enhancing the magnetic susceptibility of pyrite in run-of-mine coal through the use of selective dielectric heating. Separation of pyrite from coal would be facilitated by changing a portion of each pyrite particle to a more magnetic form. Studies included the measurement of the dielectric

Pyrite has twice as many sulfur atoms as iron atoms and therefore has one more electron involved in bonding than pyrrhotite. Pyrite has filled molecular orbitals, whereas pyrrhotite is lacking the last electron, leaving an unpaired electron in the Magnetic separators used during the study were Frantz Isodynamic Magnetic Separators, Model L-l*.

Recycling of iron from red mud by magnetic separation

Jul 20, 2014· A recycling process of iron from red mud by magnetic separation is proposed, in which iron oxide (Fe 2 O 3) in red mud transforms to magnetite (Fe 3 O 4) by anaerobic co-roasting with pyrite (FeS 2).TG-DTA and XRD results showed that hematite was reduced to magnetite by the thermo-decomposed compounds (iron monosulfide, pyrrhotite and element sulfur) of pyrite.
