Pyrrhotite Wikipedia

Pyrrhotite is an iron sulfide mineral with the formula Fe (1-x) S (x = 0 to 0.2). It is a nonstoichiometric variant of FeS, the mineral known as troilite.Pyrrhotite is also called magnetic pyrite, because the color is similar to pyrite and it is weakly magnetic.The magnetism decreases as the iron content increases, and troilite is non-magnetic.

Pyrrhotite an overview ScienceDirect Topics

G.W. Heyes, in Iron Ore, 2015. 11.3.2.3 Sulfur removal. Magnetite ores often contain sulfide minerals including pyrrhotite and pyrite. Most sulfide minerals are nonmagnetic and can be rejected by magnetic separation. Monoclinic pyrrhotite, however, in contrast to hexagonal pyrrhotite, is magnetic and is recovered in magnetic concentrates.

4 Extraction Processes for Gold-Pyrite Ore

In addition to pyrite, the ore may also contain a small amount of metal minerals such as galena, chalcopyrite, and pyrrhotite. Gangue minerals are mainly calcite and quartz. The content of pyrite is 20-45%, accounting for more than 90% of the total metal minerals. 2. The Extraction Processes of Gold-Pyrite Ore
