These encompass production processes, raw material requirements, utility requirements, infrastructure needs, machinery and technology requirements, manpower requirements, packaging requirements, transportation requirements, and more.
Magnesium hydroxide carbonate, commonly known as basic magnesium carbonate, is an industrial material utilised for its chemical stability, high absorbency, flame-retardant properties, and role as a pH regulator. In rubber and plastics production, it functions as a reinforcing filler that enhances mechanical strength while acting as a non-halogenated flame retardant and smoke suppressant, mainly in cables, automotive parts, and electric vehicle components. The compound is also used in wastewater treatment to precipitate heavy metals like lead and nickel, adjust pH levels, and facilitate desulfurisation in flue gas processes, supporting environmental protection and circular economy initiatives. In the pharmaceuticals sector, it functions as an antacid, laxative, tablet binder, and directly compressible filler for medications, while in construction, it contributes to fireproof panels, insulation, and durable building materials. Additionally, it finds uses in chemical synthesis as an intermediate for magnesium oxide production, pulp bleaching, paints and inks for whitening, ceramics and fertilisers as an anti-caking agent, and even pyrotechnics or cosmetics for texture and absorbency.
The market growth for magnesium hydroxide carbonate is driven by escalating demand in the rubber, plastics, pharmaceuticals, and construction sectors, as a reinforcing filler, flame retardant, smoke suppressant, antacid, and excipient. Additionally, rapid industrialisation and urbanisation, mainly in Asia-Pacific regions like China and India, fuel this expansion through increased production of automotive components, electric vehicle cables, flame-retardant building materials, and pharmaceutical formulations.
Moreover, environmental regulations and sustainability trends further propel adoption, as manufacturers invest in greener production methods like carbon capture and low-impact mining to meet stricter standards in Europe and North America. Its cost-effectiveness and multi-functionality, such as pH adjustment in wastewater treatment and anti-caking in fertilisers, provide stable revenue streams amid raw material price volatility. However, raw material availability and sourcing impact industrial magnesium hydroxide carbonate procurement, as the compound derives from magnesium-bearing minerals like magnesite, brucite, or seawater/brine.
Raw Material for Magnesium Hydroxide Carbonate Production
According to the magnesium hydroxide carbonate production plant project report, the various raw materials for magnesium hydroxide carbonate production include dolomite ore and white coal.
Production Process of Magnesium Hydroxide Carbonate
The extensive magnesium hydroxide carbonate production cost report consists of the following major industrial production process:
- Production via dolomite calcination-carbonation method: The production process of magnesium hydroxide carbonate begins with mixing dolomite ore (CaMg(CO3)2 and white coal in an 8-10:1 ratio as fuel. The mixing is followed by calcining the blend in a kiln at 1000-1200 degree Celsius to decompose it into dolomite clinker, primarily calcium oxide (CaO), magnesium oxide (MgO), and CO2-rich kiln gas, while driving off carbonates. In the next step, the clinker is screened, then digested in a tank with water to form ash milk, a slurry of calcium hydroxide (Ca(OH)2) and magnesium hydroxide (Mg(OH)2). The slurry is sieved and further refined into fine ash milk via multiple digestion and clarification stages to remove impurities. In the following step, purified kiln gas (high in CO2 from calcination) is fed into a carbonate tower where it carbonates the fine ash milk slurry to form soluble calcium bicarbonate and precipitates basic magnesium carbonate as a carbonation acid liquid. In the next step, the liquid undergoes clarification to yield heavy magnesium water clear liquid. Finally, the liquid is thermally decomposed via steam heating, followed by filtration, washing, dehydration, drying, and crushing to isolate high-purity magnesium hydroxide carbonate powder.
Properties of Magnesium Hydroxide Carbonate
Magnesium hydroxide carbonate, also known as basic magnesium carbonate with formulas such as (MgCO3)4·Mg(OH)2·4-5H2O, is a white, odourless powder or friable masses with a density of 2.16-3.1 g/cm³, stable in air. It is practically insoluble in water (pH ~10.5 in suspension) and alcohol, but soluble in dilute acids with CO2 effervescence. It decomposes endothermically above 300 degree Celsius into magnesium oxide, water, and carbon dioxide, lacking a distinct melting point, which supports its use as a non-toxic flame retardant. It behaves as a weak base ideal for pH regulation, antacid formulations, and heavy metal precipitation in wastewater.
