BURNT DOLOMITE CaMg(CO3)2
1. The chemical composition- Chemical formula: CaMg(CO3)2
- Name: Dolomite - natural calcium and magnesium carbonate. This mineral was named in honor of D. Dolomieu (1750 - 1801) - French Mineralogist and Chemist who discovered the new mineral on an Alps expedition. Lava containing up to 95% dolomite is also called dolomite.
- Other names: Miricalcit.
- Dolomite synonyms: Ridolfit, Taraspit.
2. Main characteristics- After burning, it is usually gray white, milk
- Due to the high content of CaO, avoid moisture

3.1 In steel and metallurgical industry
- Dolomite is added to make slag.
- Limiting the melting of furnace walls.
- De-sulfur, phosphorus
- Keep heat to liquid metal.
- Protection of liquid metals from oxidation
3.2 Agricultural- Improve and stabilize soil pH, reduce acidity, reduce acidity, loosen soil.

- Use for all crops
- Depending on the pH of the soil
- The amount of fertilizer: 150 - 250 kg / 1000m2 Before or after fertilizing for 3 to 5 weeks
3.3 In aquaculture industry- In the form of powder, the particle size of about 45 micronmeters is used to treat pond water, creating alkalinity for water, providing macronutrients and micronutrients for food in aquaculture.
3.4 Dolomite is used in the fertilizer industry
