The Química del Rey plant has the largest installed capacity for sodium sulfate production outside of China.
Our sodium sulfate operation captured an 79% market share in Mexico.
Ammonium sulfate is a value-added byproduct used as fertilizer.
The inorganic chemicals business diversifies our product line and expands our markets. We extract materials from the subsoil, such as natural brine and dolomite, and use residual sulfuric acid from the Metals division to produce supplies that have a wide variety of industrial uses and applications.
The chemical division consists of two processing plants and a chemical complex, known respectively as Fertirey, Industrias Magnelec and Química del Rey. The latter is one of Mexico’s most important and the largest sodium sulfate plant outside of China. This plant also produces magnesium sulfate and magnesium oxide.
Two sodium sulfate plants, a magnesium specialty plant and one dolomite mine
Sodium sulfate, magnesium sulfate and magnesium oxide in diverse specialties.
* Figures to December 2022
In Laguna del Rey, Coahuila, we obtain virgin brine containing sodium sulfate and magnesium salts.
The virgin brine is pumped to storage tanks, cooled and crystallized to obtain Glauber salt.
Glauber salt settles and is sent on to the washing and filtering stage.
Glauber salt is melted to obtain anhydrous sodium sulfate.
Anhydrous sodium sulfate is allowed to settle, then it is dried and stored for subsequent shipment.
