Recycling of iron from red mud by magnetic separation after co-roasting
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, …

Maceral and pyrite partitioning through high-gradient magnetic
The basic principle involved in high gradient magnetic separation (HGMS) lies in coal being diamagnetic (repulsed by a magnet) while pyrite is paramagnetic (attracted to a magnet). The mag- netic susceptibility of pyrite is 0.3 X 10-6 emu/g while this susceptibility of coal is --0.4 X 10-6 to --0.8 X 10-4 emu/g {1 emu = 1 gauss).

Is Pyrite Magnetic? (And Why?)
Why is pyrite weakly magnetic? Pyrite is weakly magnetic due to its composition and crystal structure. Pyrite is an iron sulfide mineral with a chemical formula of FeS 2. 3 The weak magnetism of pyrite is primarily attributed to the presence of iron (Fe) within its structure. Iron is a ferromagnetic material, which means it can be strongly ...
