Magnesium Chloride Dihydrate (MgCl₂·2H₂O) is a hydrated magnesium salt containing two molecules of crystallization water, widely used as a chemical intermediate, deicing agent, dust suppressant, magnesium metal feedstock, and additive in industrial processes. It is typically produced through the processing of natural brines, seawater, salt lake brines, or potash by-product streams, where magnesium-rich brine is concentrated and reacted with hydrochloric acid or recovered during potassium and sodium salt extraction. The supply chain begins with raw material extraction (seawater, underground brine, or salt lake brine), followed by brine purification, evaporation, crystallization, and controlled hydration to produce magnesium chloride in dihydrate form. The product is then processed, dried, or pelletized depending on application requirements and distributed to downstream industries including chemical manufacturing, magnesium metal production (via electrolytic processes), construction materials, deicing and dust control, water treatment, agriculture, and oil & gas drilling fluids. Major production regions include China, the United States, Israel, the Dead Sea region, and Europe, where integrated salt and mineral producers operate large-scale brine processing facilities. In 2025, global Magnesium Chloride Dihydrate output was about 650,000 tons with 1 million tons of capacity, average prices of USD 420 – 650 per ton, and gross margins around 19%.
