Magnesium Sulfate Production
Magnesium Sulfate Plant Capital & Operating Cost Analysis | United States | Q1 2026
This report presents the economics of Magnesium Sulfate production from magnesium carbonate and sulfuric acid. In the process, magnesium carbonate is treated with sulfuric acid, producing magnesium sulfate.
The report provides a comprehensive study of Magnesium Sulfate production and related Magnesium Sulfate production cost, covering three key aspects: a complete description of the Magnesium Sulfate production process examined; an in-depth analysis of the related Magnesium Sulfate plant capital cost (Capex); and an evaluation of the respective Magnesium Sulfate plant operating costs (Opex).
The Magnesium Sulfate production process description includes a block flow diagram (BFD), an overview of the industrial site installations, detailing both the process unit and the necessary infrastructure, process consumption figures and comprehensive process flow diagrams (PFD). The Magnesium Sulfate plant capital cost analysis breaks down the Capex by plant cost (i.e., ISBL, OSBL and Contingency); owner's cost; working capital; and costs incurred during industrial plant commissioning and start-up. The Magnesium Sulfate plant operating costs analysis covers operating expenses, including variable costs like raw materials and utilities, and fixed costs such as maintenance, labor, and depreciation.
Product
Magnesium Sulfate. Magnesium Sulfate (a.k.a. Epsom Salt) is a magnesium salt having sulfate as the counterion. In nature, it does not occur in its anhydrous form, only in hydrated compositions, being MgSO4.7 one of the most stable and commercially important. In many countries, MgSO4 is produced from magnesite, dolomite, seawater magnesia, or other magnesium minerals. It is used as a nutrient in agricultural operations and as an effective laxative. It is administered intravenously for sea sickness, and hypertension, and to lower intracranial pressure. Magnesium Sulfate is recognized by the WHO as the safest, most effective, and lowest-cost medicine for treating pre-eclampsia and eclampsia.
Raw Materials
Sulfuric Acid. Sulfuric acid is one of the most widely used industrial chemicals, serving as a key component in fertilizer production, mineral processing, and chemical manufacturing. It is also used in the refining of petroleum and metal ores. Sulfuric acid is produced via the contact process, where sulfur dioxide is oxidized and absorbed in water. It is stored as a liquid and is crucial for processes like phosphate fertilizer production and in lead-acid batteries.
Magnesium Carbonate. Magnesium carbonate is an inorganic compound used as a filler in rubber and plastics, as a fireproofing agent, and as a drying agent in athletic applications. It is also employed in pharmaceuticals and cosmetics. Mined from natural deposits or produced synthetically, it is stored as a white powder.

Sulfuric Acid from Sulfur (Single-Contact Process)
This report presents the economics of Sulfuric Acid production from sulfur in the United States. In this process, sulfur is burned to form sulfur dioxide, which is then converted to sulfur trioxide. This sulfur trioxide is converted to sulfuric acid by absorption with recirculating sulfuric acid solution in water in only one column.

Sulfuric Acid from Spent Acid (Wet Gas Sulfuric Acid Process)
This report presents the economics of spent sulfuric acid regeneration via wet sulfuric acid (WSA) process in the United States. In this process, spent acid is decomposed to form sulfur dioxide and water. The sulfur dioxide is oxidized to sulfur trioxide, which is then regenerated to sulfuric acid by vapor-phase reaction with water.
