    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 ...

    en.wikipedia.org/wiki/Zinc_smelting

    The sphalerite ore found here was presumably converted to zinc oxide via roasting, although no archaeological evidence of this has been found. Smelting is thought to have been done in sealed cylindrical clay retorts which were packed with a mixture of roasted ore, dolomite , and an organic material, perhaps cow dung , and then placed vertically ...

    en.wikipedia.org/wiki/Wurtzite

    Wurtzite is a zinc and iron sulfide mineral with the chemical formula (Zn,Fe)S, a less frequently encountered structural polymorph form of sphalerite. The iron content is variable up to eight percent. [5] It is trimorphous with matraite and sphalerite. [2] It occurs in hydrothermal deposits associated with sphalerite, pyrite, chalcopyrite ...

    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.
