WhatsappZinc Sulphate Manufacturing process
Step 1: Raw Material Selection
High-purity zinc oxide (ZnO) or zinc carbonate (ZnCO₃) and sulfuric acid (H₂SO₄) are used.
Raw materials undergo strict quality checks for purity.
Step 2: Chemical Reaction & Processing
Zinc oxide/carbonate reacts with sulfuric acid to form Zinc Sulphate solution.
The solution is filtered and refined to remove impurities.
Step 3: Crystallization & Drying
The solution is evaporated, crystallized, and dried to achieve the required purity.
Step 4: Quality Control & Testing
The product is tested for assay, solubility, moisture content, and pH as per IP/BP/USP standards.
Step 5: Packaging & Storage
Packed in HDPE bags or fiber drums to prevent contamination.
Stored in a cool, dry place to maintain stability.
