Magnesium Sulphate Anhydrous Manufacturing Process

Magnesium Sulphate Anhydrous (MgSO₄) is produced from either natural sources like kieserite, carnallite, or magnesium-rich brines, or chemical processes using magnesium salts and sulfuric acid. The manufacturing involves the following key steps:


1. Raw Material Selection

High-purity magnesium sources (e.g., magnesium carbonate, magnesium hydroxide, or magnesium chloride) are selected along with sulfuric acid of the required concentration. Quality of raw materials ensures purity of the final product.

2. Reaction Process

The raw magnesium compound is reacted with concentrated sulfuric acid under controlled temperature:

  • MgO / Mg(OH)₂ + H₂SO₄ → MgSO₄ + H₂O
  • MgCO₃ + H₂SO₄ → MgSO₄ + CO₂ + H₂O

This produces magnesium Sulphate in solution.

3. Filtration & Purification

Impurities are removed through filtration, ensuring the solution is free from insoluble residues or other contaminants.

4. Concentration & Crystallization

The filtered solution is evaporated to remove water, leading to the formation of anhydrous MgSO₄ crystals. Precise control of temperature and evaporation rate ensures uniform crystal size.

5. Drying

Crystals are dried using rotary dryers or fluidized bed dryers to obtain completely anhydrous magnesium Sulphate. Moisture content is kept minimal to meet industrial and pharmaceutical standards.

6. Milling & Packaging

The dry crystals may be milled or granulated for ease of handling and packaging. The final product is packed in moisture-proof containers for storage and shipment.
