Aluminum Bauxite Ore:
The primary aluminum-bearing ore, mainly composed of:
Aluminum oxide (Al₂O₃): 30-60%
Iron oxide (Fe₂O₃): 5-30% (gives red/brown coloration)
Impurities (SiO₂, TiO₂...)
Key Characteristics:
Lateritic (tropical regions) or karst (limestone) formations
Extracted via open-pit mining, requires refining into alumina (Al₂O₃) before aluminum production
Primary Applications:
Raw material for aluminum production (90%)
Refractory materials, water treatment, chemical manufacturing
Major Deposits: Australia, Guinea, Vietnam, Brazil.
Overview:
Vy An Group is a pioneering enterprise in iron ore mining and export in Vietnam, sourcing high-quality raw materials from premium deposits in Thach Khe (Ha Tinh), Lao Cai, and Yen Bai...
Key Export Products:
Concentrated Iron Ore (Fe 50-65%): Processed to meet international standards.
Lumps & Fines: Various sizes tailored to importers' needs.

Silica Sand
Silica sand is a type of sand primarily composed of silicon dioxide (SiO₂), commonly found in quartz rock, beaches, and mineral deposits.
Characteristics
- High Purity: Contains at least 95% SiO₂ with minimal impurities.
- Hardness: Rated 7/10 on the Mohs scale, making it highly durable.
- Chemical Inertness: Does not react with most substances.
Applications
- Glass Manufacturing: Key raw material for producing glass, bottles, and windows.
- Water Filtration: Used as an effective filtration medium.
- Construction: Utilized in concrete, cement, and bricks.
- Industrial Use: Found in ceramics, paints, and metallurgy.
White Marble:
White marble is a natural stone with a pure white or cloud-like veined appearance, commonly used in construction, interior decoration, and high-end material production.
Characteristics
- Main Composition: Primarily composed of calcium carbonate (CaCO₃).
- Color: Bright white, often featuring natural gray, brown, or green veining.
- Durability: High strength, good wear resistance.
- Applications: Used for flooring, countertops, staircases, and exterior facades.
Popular Types of White Marble
- Italian White Marble: Imported from Italy, features elegant natural veins in soft gray-brown shades.
- Pure White Marble: Completely white with no veins, ideal for minimalistic designs.
- Cloud Vein White Marble (Volakas): Originating from Greece, showcasing soft flowing veins in gray, brown, purple, or pink hues.
