WebZinc sulfate is a combination of sulfur and zinc. It is an herbicide typically used for moss control. The toxicity of zinc sulfate depends on the amount of zinc in the product. Zinc is an essential mineral for human, animal, and plant nutrition. Zinc can be found naturally in the environment, foods, and water. 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.
