به خواندن ادامه دهیدThis amazing piece of copper ore is from the Talnakh Copper-Nickel Deposit in Siberia. The rock is dominated by pyrrhotite (Fe(1-x)S - imperfect iron monosulfide), which is a washed-out brassy color, and chalcopyrite (CuFeS2 - copper iron sulfide), which is a yellow-brassy color. The scattered black crystals are magnetite (Fe3O4 - iron oxide).

به خواندن ادامه دهیدPyrrhotite 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.

به خواندن ادامه دهیدMagnetic 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.
