Zinc carbonate is a white, insoluble, zinc salt with chemical formula Zn CO 3.With it, most simple zinc salts can be made by reaction with the corresponding proportions of sulfate. Smithsonite is named for James Smithson, the English founder of the Smithsonian Institution who first identified the mineral. Terms and keywords related to: Aurichalcite Hydrozincite. Although it rarely forms crystals, smithsonite is most commonly found as botryoidal or stalactitic masses or as honeycombed aggregates. It takes its name from the Greek word σίδηρος sideros, ... Malachite, azurite, cuprite Cu 2 O, pyromorphite Pb 5 (PO 4 ) 3 Cl and smithsonite ZnCO 3 are stable in oxidising conditions and they are characteristic of the oxidation zone. Origin of Name & Mythology: The carbonate "calamine" was re-named smithsonite in 1832 by François Sulpice Beudant in honor of James Smithson [1754-1829], British chemist, mineralogist, and benefactor of the Smithsonian Institution (Washington, DC, USA). Smithsonite chemical formula is ZnCO 3 (zinc carbonate). During that time, Smithsonite was generally known as calamine.. Metalworkers and miners knew that some forms of calamine produced zinc, but Smithson’s studies revealed that this mineral they called calamine was made up of two distinct minerals. Although a member of the calcite group, it rarely displays a rhombohedral form, occurring instead as botryoidal or reniform masses, and less often as spherulitic, earthy or massive clusters.
