Magnesium Hydroxide used in many
industry applications

Magnesium hydroxide is a white powder known chemically as Mg(OH)2 and commonly found in nature as the mineral brucite. It is widely used in various industrial applications due to its fire retardant properties, alkalinity, and as a source of magnesium. Here are some of its main industrial uses:

  1. Wastewater Treatment: It is used to neutralize acidic wastewaters and remove impurities through precipitation, improving water quality before discharge.
  2. Fire Retardants: Magnesium hydroxide is added to plastics, rubbers, and coatings as a fire retardant. It decomposes at high temperatures, releasing water which helps to cool and slow the spread of fire.
  3. Pharmaceuticals: In the pharmaceutical industry, it serves as an antacid and laxative to relieve symptoms of indigestion and heartburn by neutralizing stomach acid.
  4. Flue Gas Desulfurization: It is used in power plants and industrial facilities to scrub sulfur dioxide (SO2) from exhaust gases, preventing its release into the atmosphere.
  5. Pulp and Paper Industry: Magnesium hydroxide is used as a bleaching agent in the production of pulp and paper, contributing to the whitening process without the use of chlorine.
  6. Food Additive: It acts as an anti-caking agent in food products, preventing ingredients from clumping together and ensuring smooth consistency.
  7. Personal Care Products: Due to its gentle basicity and non-toxic properties, magnesium hydroxide is used in deodorants and some antiperspirants as an alternative to aluminum-based compounds.
  8. Chemical Industry: It serves as a source of magnesium in the production of other magnesium compounds and can be used as a catalyst or stabilizer in various chemical reactions.
  9. Environmental Remediation: Magnesium hydroxide is used in the treatment of acid mine drainage and as a heavy metal adsorbent in contaminated soils and water.
