Used as a dietary supplement in animal feed to prevent zinc deficiency and support growth, immune function, and skin health in livestock and poultry. Commonly applied in agriculture as a micronutrient fertilizer to correct zinc deficiency in soils, improving crop yield and quality, especially in zinc-sensitive plants like corn, rice, and citrus. Employed in the textile industry for bleaching and weighting cotton, and as a mordant in dyeing processes to improve color fastness. Utilized in the manufacture of rayon and other synthetic fibers to stabilize chemical reactions during production. Serves as an electrolyte in zinc electroplating baths to coat metals with a protective zinc layer, enhancing corrosion resistance. Found in some medicinal formulations for treating zinc deficiency in humans and used in eye drops for certain ocular conditions due to its astringent and anti-inflammatory properties. Also used in the preservation of wood and in some water treatment processes to control algae and microbial growth.
