Web9 de ago. de 2024 · Zinc sulfide is an inorganic compound with the chemical formula of ZnS, and its molar mass is 97.47 g/mol. The chemical structure of ZnS is simple and consists of the zinc metal attached to a sulfur atom through a polar covalent bond. This is the main form of zinc found in nature, where it mainly occurs as the mineral sphalerite. WebZinc can be obtained by electrolysis of zinc sulfate or by smelting in a process similar to the production of iron from the blast furnace. First the zinc ore is roasted in air, converting it to zinc oxide: 2ZnS(s) + 3O 2 (g) → 2ZnO(s) + 2SO 2 (g) Coke and the roasted ore are fed into the top of the furnace with air blasted in at the bottom.
