Calcined Dolomite - Burnt Dolomite

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. Application of Dolomite

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

Agricultural

• Improve and stabilize soil pH, reduce acidity, reduce acidity, loosen soil.
• Restrict, inhibit the growth of insects, nematodes, fungal damage the root system, which helps develop a healthy root system, antibacterial.
• Helping plants avoid yellowing, falling young fruit, caused by lack of calcium and magnesium.
• Provide adequate secondary substances calcium, magnesium for soil and plants, make plants strong photosynthesis, increase productivity and quality of agricultural products.
• 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      

Calcined dolomite is obtained by the calcination of dolomite, with a high content in calcium and magnesium carbonate CaMg(CO3)2 

This product has mainly steel applications to improve slagging and to lengthen the lifespan of the refractory linings of ovens and ladles. Also, in metallurgy, chemistry, manufacture of refractory bricks and in stabilization in the process of manufacture of glass, improving its resistance to the aggression of gases and humidity.  It can also be used in waste water and sludge treatment, as well as in fertilization and conditioning of terrains.
