Beneficiation of pyrite from coal mining - ScienceDirect

Dec 15, 2016  1. Introduction. Pyrite, a mineral with a chemical formula of FeS 2, is an iron disulfide, which is usually associated with other sulfides and oxides.It is abundant in the earth's surface, being found in the composition of sedimentary and metamorphic rocks, in coal beds and as a replacement mineral in fossils (Klein and Hurlbut, 1993).There are occurrences of high crystallinity pyrite in the ...

Sep 17, 2019  Pyrite (FeS 2) is the most common sulfide mineral in coal and a major source of the sulfur in coal.Pyrite can form in peat while the peat is accumulating, or can form in peats from the introduction of sulfate (SO 4) into the peat if the peat was buried by marine waters (such pyrite is called syngenetic or authigenic pyrite).Within the buried peat, the sulfate is reduced to sulfide (S 2), which ...

Effect of Pyrite Ore in Direct Coal Liquefaction Process ...

The catalytic activity of pyrite ore from coal mining was studied in the direct liquefaction process of high volatile bituminous coal from the south of Brazil. The process consisted of mixing pulverized coal with tetralin in the presence of catalyst. It was possible to obtain fractions of

Effects of pyrite on the spontaneous combustion of coal ...

Sep 28, 2015  Pyrite has a significant effect on the spontaneous combustion of coal. The presence of pyrite can change the propensity of coal towards spontaneous combustion. The influences of various pyrite contents on the parameters of spontaneous combustion, such as index gases, temperature and released heat etc., were investigated in this study. Coal samples with different pyrite contents (0 %, 3

Removal of Pyrite in Coal Flotation: Mineral Processing ...

Apr 25, 2007  In most operating coal-cleaning plants, a significant amount of pyrite is recovered in the froth during flotation of high-sulfur coal. Reducing the pyrite recovery first requires that the primary recovery mechanism should be identified, as different measures are required for reducing entrainment, locked-particle flotation, or true hydrophobic flotation.
