PYRITE (Iron Sulfide)

Pyrite is a polymorph of marcasite, which means that it has the same chemistry, FeS2, as marcasite; but a different structure and therefore different symmetry and crystal shapes. Pyrite is difficult to distinguish from marcasite when a lack of clear indicators exists. Pyrite's structure is analogous to galena's structure with a formula of PbS Get price

Fluor

Fluor-uvite is a tourmaline mineral with the chemical formula CaMg 3 (Al 5 Mg)(Si 6 O 18)(BO 3) 3 (OH) 3 F. It is a rare mineral that is found in calcium-rich contact metamorphic rocks with increased amounts of boron. Uvite is trigonal hexagonal, which means that it has three equal length axes at 120 degrees, all perpendicular to its fourth axis which has a different length. Get price

Pyrrhotite

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.

Mend

Unlike pyrite, pyrrhotite represents a range of chemical composition as indicated by the formula Fe1-xS in which x can vary from 0 to 0.125. This also implies that there is an inherent deficiency of iron in the crystal structure, possibly representing less structural stability than that of pyrite.

Difference Between Pyrite and Galena

The chemical formula of pyrite is FeS2; it is sulfide compound of iron where as galena is sulfide compound of lead with the chemical formula PbS. The color of galena may vary from light gray to dark gray while pyrite is generally brass yellow in color. For this reason pyrite also termed as fool's gold. Get price
