Manufacturing Process of Magnesium Sulfate Heptahydrate

This report comprises a thorough value chain evaluation for Magnesium Sulfate Heptahydrate manufacturing and consists of an in-depth production cost analysis revolving around industrial Magnesium Sulfate Heptahydrate manufacturing.

• Production from Anhydrous Calcium Magnesium Carbonate and Sulfuric Acid: The industrial manufacturing process for Magnesium Sulfate Heptahydrate begins with the preparation of a mineral called anhydrous calcium magnesium carbonate. The feedstock for this process is this mineral and sulfuric acid. In the first step, the mineral is ground to a fine powder to increase its surface area. The powder is then subjected to calcination in a kiln at high temperatures, which causes it to decompose into magnesium oxide and calcium oxide. This magnesium oxide is then reacted with sulfuric acid, which forms a solution of magnesium sulfate. This solution is further concentrated and cooled in a crystalliser to allow the crystals of Magnesium Sulfate Heptahydrate to form. These crystals are then filtered to remove the mother liquor and dried to a specific moisture content, giving us the final fertiliser-grade product.
