Apatite is the most common phosphate mineral, and is the main source of the phosphorus required by plants. The bones and teeth of most animals, including humans, are composed of calcium phosphate, which is the same material as Apatite. (These biological Apatites are almost exclusively the Hydroxylapatite type.) Chemical Formula.The chemical formula of the sphalerite is ZnS in its pure form. It consists of 67% of zinc and 33% of sulphur. Sphalerite is used worldwide for zinc extraction, which in turn is used to make products, chemicals and medicines. The general chemical formula of sphalerite is written (Zn,Fe)S to imply that the ratio of the two metals (Zn and Fe) is variable from one specimen to other, but the ratio of total metal to S remains constant. Zinc is ordinarily present in greater amount than Fe (Krauskopf 1979).The resulting formula was anticipated above. • Chemical analyses obtained with an electron microprobe (wavelength dispersive) or energy dispersive x-ray spectrometer do not distinguish between the oxidation state of elements such as iron that occur in more than one valence state. For minerals that contain iron, the ferric/ferrousTroilite 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. The value of "X" in the chemical formula of pyrrhotite can range between 1 and 0.17.The chemical formula for sphalerite is (Zn, Fe)S. The chemical composition is also listed below.Zinc is recovered from a number of different zinc minerals. The most significant of these is sphalerite.
