What Is Barite Powder?

Barite powder is a finely ground form of natural barium sulfate (BaSO₄), processed to meet industry-specific purity and particle size requirements.

Key Properties of Barite Powder

✔ High density (4.2–4.5 g/cm³) – Ideal for drilling fluids
✔ Chemical inertness – Resistant to acids and alkalis
✔ Brightness & whiteness (85–95%) – Used in paints and coatings
✔ Low solubility – Safe for medical and food-grade applications

Common Grades of Barite Powder

Production Process: From Ore to Powder

1. Mining & Extraction

Barite is sourced from:

• Vein deposits (high-grade, underground mining)

• Bedded deposits (sedimentary layers, open-pit mining)

• Residual deposits (weathering zones)

Top Producing Countries:

• China (~40% of global supply)

• India, Morocco, USA, Mexico

2. Processing & Beneficiation

1. Crushing & Grinding → Ore is reduced to small particles.

2. Gravity Separation → Removes impurities (silica, iron).

3. Flotation (if needed) → Enhances BaSO₄ purity.

4. Drying & Milling → Produces fine powder (200-500 mesh).

5. Quality Testing → Ensures API/industry compliance.

3. Packaging & Distribution

• Bulk bags (1-ton) for industrial use

• 25-50 kg bags for chemical/pharma sectors
