Manufacturing process of Calamine
Step 1: Raw Material Selection
- High-purity zinc oxide (ZnO) and ferric oxide (Fe₂O₃) are selected.
- Raw materials undergo strict quality checks for purity.
Step 2: Blending & Mixing
- Zinc oxide and ferric oxide are blended uniformly under controlled conditions.
- Ensures consistent particle size and even distribution of ferric oxide for the pink color.
Step 3: Milling & Sieving
- The blended material is milled and sieved to achieve the desired fine particle size.
Step 4: Quality Control & Testing
- The final product is tested for assay, particle size, pH, moisture content, and purity 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 for maintaining stability.
