The performance of naturally derived pyrrhotite for Hg 0 capture from the flue gas was much better than those of other reported magnetic sorbents, for example Mn-Fe spinel and Mn-Fe-Ti spinel. The rate of pyrrhotite for gaseous Hg 0 capture at 60 °C was 0.28 μg g min -1 and its capacity was 0.22 mg g -1 with the breakthrough threshold of 4%.

1 INTRODUCTION. The magnetic properties of the iron oxides and sulphides magnetite (Fe 3 O 4), hematite (αFe 2 O 3) and monoclinic 4C pyrrhotite (Fe 7 S 8) at above-ambient temperatures T govern their magnetic expression at depth in the Earth and other planets, fore example, Mars. They also determine the magnetic memory these …

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.

Bacteria are major mediators in the deposition of many nonmagnetic oxyhydroxide iron minerals such as ferrihydrite and goethite, but some form the iron oxide magnetite, Fe 3 O 4 (see Figure 6), or the magnetic iron sulfides, greigite, Fe 3 S 4, and pyrrhotite, Fe 7 S 8.The location of these minerals may be intracellular (biologically controlled), or …

Magnetic Properties of Pyrrhotite. Pyrrhotite is similar to another iron sulfide mineral named troilite. Troilite has a chemical composition of FeS, while pyrrhotite's chemical composition is Fe (1-x) S. Pyrrhotite is deficient in iron because some of the iron sites in its crystal lattice are vacant (empty). That is why the iron in the formula has a subscript of 1-x.
