Magnesium chloride is widely used for dust control and road stabilization, especially on unpaved roads and construction sites. It helps bind fine particles together, reducing airborne dust and improving surface durability. In agriculture, it serves as a source of magnesium for plants, correcting magnesium deficiency in soils, particularly in crops like tomatoes and potatoes. It is also used in the production of fertilizers. In food processing, magnesium chloride is used as a coagulant in tofu production, helping soy milk solidify into curds. It plays a role in industrial applications such as wastewater treatment, where it aids in phosphorus removal, and in the production of other magnesium compounds. Additionally, magnesium chloride is used in some medical and dietary supplements due to its high bioavailability, supporting muscle and nerve function, and maintaining electrolyte balance. It is also employed as a de-icing agent on roads and sidewalks in cold climates, lowering the freezing point of water and melting ice more effectively than salt alone.
