Moreover, the bacterial production of magnetite may represent a significant contribution to the natural remanent magnetism of sediments 4,5. Here we report, the intracellular biomineralization of single crystals of the ferrimagnetic iron sulphide, greigite (Fe 3 S 4 ), in a multicellular magnetotactic bacterium common in brackish, sulphiderich water and sediment.

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

Large crystals of the bronzeyellow colored mineral pyrite are present in this sample. Pyrite (FeS2) is composed of both iron and sulphur. Its bronzeyellow color often causes pyrite to be mistaken for gold, and a common name for pyrite is "fool's gold".

In this schist, the mineral magnetite occurs as black "knots" or porphyroblasts in a finergrained matrix composed of muscovite, chlorite, quartz, and albite. Small grains of pyrite and garnet are present in some samples. The magnetite is strongly magnetic and will be attracted by a small hand magnet.

Pyrite + Oxygen + Water => Ferrous Iron + Sulfate + Acidity . The second reaction involves the conversion of ferrous iron to ferric iron. The conversion of ferrous iron to ferric iron consumes one mole of acidity. Certain bacteria increase the rate of oxidation from ferrous to ferric iron.

The sulfur content of coal treated in accordance with this method can be reduced by subjecting the treated coal to a lowstrength magnetic field for moving at least 50% by weight of the pyrite from the coal although a smaller fraction, about 5 to 25%, of the pyrite is actually converted to magnetite.

The activity of strongly reducing ligands (, catechol) or unsaturated Fe(III)exchange capacity (particularly in experiments with bentonite or with solutions of uncomplexed ligands) can result in an effective reduction of ferric iron concentration and prevent pyrite dissolution and/or interfere with the crystallization of magnetite.

The mineral pyrite, or iron pyrite, is iron disulfide, FeS2. It has isometric crystals that appear as cubes or pyritohedrons (twelve irregular, pentagonal or fivesided faces). Pyrite takes its name from the Greek word 'pyros' meaning 'fire' because sparks flew from it when hit with another mineral or a metal.

Pyrite is found all over the world in igneous, metamorphic and sedimentary rocks. It occurs as cubic, pyritohedra (meaning 12 faces, each with 5 edges) or octahedral crystals. The crystal faces are often striated. Pyrite can be massive, granular, reinform, stalactitic, botryoidal and nodular.
