Preparation of Metallic Iron Powder from Pyrite Cinder by ...

Abstract: The reduction and magnetic separation procedure of pyrite cinder in the presence of a borax additive was performed for the preparation of reduced powder. The effects of borax dosage, reduction temperature, reduction time and grinding ﬁneness were investigated. The results show that when pyrite cinder briquettes with 5% borax were preoxidized at 1050 C for 10 min, and reduced at ...

Principles of Magnetic Separation

Magnetic separation may be used for coal beneficiation when the gangue minerals contain such iron phases, however their very weak magnetic susceptibilities would require strong magnetic field strength (Dwari and Rao, 2009). Previous works on the magnetic separation of pyrite from coal have shown pyrite to be a weakly paramagnetic mineral ...

Magnetic separation of minerals is a topic that is seldom reported in the literature for two reasons. First, ... 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 highest orbital. Readers are ...
