Application
-
Agricultural Sector:
Serves as a popular zinc fertilizer compatible with base application, topdressing, seed soaking, and foliar spraying. It effectively cures zinc deficiency, stimulates chlorophyll formation, and elevates overall crop yield by 15% to 27%. -
Industrial Manufacturing:
Applied as an essential raw material for lithopone pigments, specialty zinc salts, and industrial inks, as well as a printing and dyeing mordant, wood preservative, and additive in viscose fiber manufacturing. -
Wastewater Treatment:
Functions as an efficient flocculant and heavy metal precipitant in industrial wastewater management to remove suspended solids and capture toxic contaminants. -
Feed Industry:
Acts as a highly bioavailable trace zinc supplement that enhances immune functions, enzymatic systems, and skeletal development across poultry and livestock species.
