Magnesium hydroxide is a colorless hexagonal crystal or white powder, which is widely used in many fields. Some people have consulted the steps of magnesium hydroxide ingredients, so today we will give a detailed description of this.
1. Magnesium hydroxide is calcined from magnesite as the main raw material in the traditional carbonation kiln.
2. After removing impurities from ferric hydroxide by filtration, soluble magnesium hydroxide is added, and 25-28% ammonia brine is added at the same time. After dilution and pyrolysis for 1.5 hours, magnesium hydroxide is formed.
3. Making the above-mentioned magnesium oxide into slurry;
4. Magnesium carbonate is put into an acid solution with a concentration of 98. The soluble magnesium hydroxide is hydrolyzed by acid and then oxidizer with a weight ratio of 2% to 3 is added to the mixed acid solution to oxidize ferrous oxide into ferric hydroxide.
5. Put the slurry into the carbonization tower to carbonize and reduce the slurry to magnesium carbonate.
The ingredient steps of magnesium hydroxide are introduced here, hoping to be helpful to everyone.
