The Production Methods of Using Magnesium Hydroxide and Magnesium Oxide as Raw Materials

Maybe you are not very understanding the production methods of using magnesium hydroxide and magnesium oxide as raw materials. Now we will talk something about those methods.

1. After magnesium hydroxide filter press, light burning or drying below 350℃, it will be made of light magnesium oxide or magnesium hydroxide. This method not only improves the resource utilization of magnesite, but also ensure the product quality, having the advantages of saving energy and reducing consumption, not polluting the environment.

2. Put magnesite as raw material in a traditional carbonization kiln to produce calcined 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, produce magnesium hydroxide.

4. Made the above magnesium oxide into paste.

5. The concentration of magnesium carbonate into 98 °of the acid solution, the acid solution into soluble magnesium hydroxide, and then added in a mixed acid solution in a weight ratio of 2-3 ‰ oxidizer， make the solution of ferrous iron is oxidized into hydrogen iron.

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