Sphalerite is a sulfide mineral with the chemical formula (Zn, Fe)S. [5] It is the most important ore of zinc . Sphalerite is found in a variety of deposit types, but it is primarily in sedimentary exhalative , Mississippi-Valley type , and volcanogenic massive sulfide deposits.
Sphalerite is also distinctive in being moderately heavy for its size and having six different planes of cleavage. Sphalerite is the most important zinc ore mineral. Zinc produced from sphalerite is used for many purposes, including mixing with copper to produce brass, rust protection of iron & steel, and for making modern American pennies ...
Structure of Hawleyite. Hawleyite is a rare sulfide mineral in the sphalerite group, dimorphous and easily confused with greenockite.Chemically, it is cadmium sulfide, and occurs as a bright yellow coating on sphalerite or siderite in vugs, deposited by meteoric water.
He is credited with coining the mineral terms: pyrargyrite (1831), ozokerite (1833), sepiolite (1847), halite (1847), sphalerite (1847), arsenopyrite (1847), and liparite (1847). [2] He also conducted research in the field of botany — in 1836, paleobotanist Heinrich Göppert named the plant genus Glockeria in his honor.

The zinc in sphalerite is also used to produce brass. This sample was extracted in Creede, Colorado, and features black tetrahedral crystals of sphalerite up to 8 mm (0.31 in) in size, with minor chalcopyrite and calcite, in a 4.5 cm × 3.0 cm × 2.0 cm (1.77 in × 1.18 in × 0.79 in) matrix.
