Zinc sulfate, a versatile inorganic compound, plays significant roles across a wide range of sectors. In agriculture and horticulture, it acts as a primary source of zinc for plants, correcting zinc deficiencies and thereby improving growth, product quality, and shelf life. It also enhances zinc availability for plants in alkaline or calcareous soils. In the chemical industry, zinc sulfate is used in the production of zinc oxide and other zinc salts, such as zinc carbonate and zinc phosphate, which are widely applied in the manufacture of paints, rubber products, and cosmetics. In the pharmaceutical and food sectors, it is utilized as a dietary supplement in vitamins and immune‑boosting tablets, as well as in formulations of skin‑repair ointments. In water treatment and environmental applications, zinc sulfate functions as an algaecide for controlling algae growth and is employed in processes for removing heavy metals from industrial wastewater. In the metal and coating industries, it is used in electroplating (galvanizing) operations to protect iron and steel against corrosion, and in the production of anti‑rust paints and protective coatings. Additionally, zinc sulfate is applied as a catalyst in plastic and rubber industries, in paper manufacturing for color fixation, and in the formulation of certain insecticides and fungicides.
