Magnesium Hydroxide and Light Magnesium Oxide

The relationship between magnesium hydroxide and light magnesium oxide. In the production progress, they can realize transformation in different conditions.

1.After magnesium hydroxide filter press, light burning or drying oven under 350 ℃ or less , made of light magnesium oxide or magnesium hydroxide. This method, not only improves the resource utilization of magnesite, but also ensures the products quality. It has the advantages of saving energy and reducing consumption, no pollution to environment.

2.It is based on magnesite as raw material, then be put in traditional carbonization kiln, finally calcined generate magnesium oxide.

3.Filter to remove impurities such as iron hydroxide, then add soluble magnesium hydroxide, and at the same time to join concentration of 25-28% of the ammonia brine, dilution pyrolysis 1.5 hours, generate into the magnesium hydroxide.

4.Make magnesium oxide above into paste.

5.Put magnesium carbonate in acid solution concentration of 98°, after acid solution into soluble magnesium hydroxide, then add weight ratio in mixed acid solution for 2-3 ‰ antioxidant, make its solution of ferrous is oxidized to ferric hydroxide.

6.Put the slurry in the tower to make pulp reduction carbide carbide into magnesium carbonate.
