How is zincite formed
Zincite is the mineral form of zinc oxide (ZnO). Its crystal form is rare in nature; a notable exception to this is at the Franklin and Sterling Hill Mines in New Jersey, an area also famed for its many fluorescent minerals. It has a hexagonal crystal structure and a color that depends on the presence of impurities. The … Meer weergeven • List of minerals • Oleg Losev Meer weergeven • Mineral galleries Meer weergeven WebZincite is sometimes formed also in zinc smelters, because liquid zinc (melting point 419.6°C) evaporates easily (boiling point 908°C under atmospheric pressure) and reacts with oxygen if air is introduced through leaks. Such "artificial zincite" needles are sometimes more than 5 cm long.
