These encompass production processes, raw material requirements, utility requirements, infrastructure needs, machinery and technology requirements, manpower requirements, packaging requirements, transportation requirements, and more.

Magnesium chloride hexahydrate (MgCl2·6H2O) is an industrial chemical utilised for its hygroscopic nature, high solubility, and role as a magnesium ion source. In the construction sector, it functions as a major component in Sorel cement, formed by reacting with magnesium oxide, for durable flooring, fire-resistant panels, and artificial marble. It also stabilises roads and soils by enhancing cohesion and reducing erosion. It is also used in dust suppression on construction sites, mines, and unpaved roads by binding particles, and as an effective de-icing agent that melts ice at low temperatures with less corrosion and environmental harm than sodium chloride. In chemical processing, it acts as a precursor for magnesium metal smelting, magnesia production, flame retardants, textile dye fixatives, paper production, catalysts, and wastewater treatment via coagulation. Additionally, it finds application in refrigeration brines, animal feed supplements, pharmaceuticals like electrolyte solutions and laxatives, adhesives, brake pads, and light industries such as rubber, ceramics, and fuel cells.

The global magnesium chloride hexahydrate market is driven by rising demand in food processing as a nutritional supplement and preservative, chemical production as a dehydrating agent and catalyst, and pharmaceuticals for drug formulations. Infrastructure development boosts its use in construction for dust control, de-icing, and cement production, while expanding biotech and wastewater treatment sectors also add to demand. Health awareness addressing magnesium deficiencies, industrialisation in Asia-Pacific (especially China and India), and technological advancements in production efficiency further propel growth. However, regulatory approvals, environmental clearances, and safety data sheets (SDS) impact industrial magnesium chloride hexahydrate procurement, mainly for food/pharma applications requiring low impurities. Moreover, supplier reputation, production capacity, and diversified portfolios mitigate risks from supply instability or raw material shortages (e.g., brine/seawater sources). Furthermore, packaging options (flakes, crystals, prills), shelf life, and logistics (e.g., pan-India delivery) influence the overall procurement, along with ISO certifications and compliance with environmental/factory licenses.

Raw Material for Magnesium Chloride Hexahydrate Production

According to the magnesium chloride hexahydrate production plant project report, the various raw materials for magnesium chloride hexahydrate production include magnesite and aqueous hydrochloric acid.

Production Process of Magnesium Chloride Hexahydrate

The extensive magnesium chloride hexahydrate production cost report consists of the following major industrial production process:

1. Production via a semi-continuous process: The production process of magnesium chloride hexahydrate occurs through a semi-continuous process starting with leaching magnesite (MgCO3) using aqueous hydrochloric acid. The reaction is followed by purification of the raw solution via oxidation with hydrogen peroxide and neutralisation with magnesium hydroxide to remove cationic impurities. The purified solution undergoes pH adjustment, homogenisation, ultra-fine filtration, and evaporation, leading to crystallisation from mother liquor, crystal separation, partial drying, and packaging. Finally, mother liquors are recycled back to the purification step for subsequent batches, ensuring efficient resource use and high-purity output suitable for industrial applications.

Magnesium chloride hexahydrate (MgCl2·6H2O) is a colourless to white, highly deliquescent crystalline solid (density ~1.57 g/cm³) with a monoclinic structure, appearing as flakes or granules that readily absorb atmospheric moisture to form solutions. It has high water solubility (~167 g/100 mL at 20 degree Celsius), moderate ethanol solubility, a melting point of 116-118 degree Celsius (with initial dehydration), and thermal decomposition above 117 degree Celsius into MgO, HCl, and oxychloride. Its aqueous solution maintains a neutral to slightly acidic pH (6.0-7.0). It dissociates into Mg²⁺ and Cl^- ions in water as a strong electrolyte and Lewis acid, remaining stable under ambient conditions but reacting incompatibly with strong oxidisers or bases.
