Products / Bauxite

Origin: Guinea / India / Ghana / Tanzania

Bauxite is the primary raw material for alumina and aluminium production, valued for its alumina content and metallurgical stability. AMK Global supplies high grade Guinea bauxite as well as commercial grade bauxite from India, Ghana, and Tanzania to meet diverse refinery and industrial requirements.

We develop sustainable, long term supply chains of bauxite — delivering material directly from the mines to refineries and end users with reliability, consistency, and full logistical support.

Raw Bauxite Specifications

Guinea – High Grade Bauxite

• Al₂O₃: ~46%.
• Silica (SiO₂): ~2.5%.
• Moisture: 10-12%.
• Size: 0-100 mm (custom sizing available).

India / Ghana / Tanzania – Commercial Grade

• Al₂O₃: 40-44%.
• Silica (SiO₂): Higher silica ranges depending on origin (3 to 8%).
• Moisture: 10-12%.
• Size: 0-100.

Calcined Bauxite

Origin: India / China / Global Sources

Calcined Bauxite is produced by heating high grade bauxite at elevated temperatures to remove moisture and volatile components, resulting in a hard, dense, and highly durable material. It is used in refractories, abrasives, road surfacing, and specialized high temperature industrial applications.

We also supply calcined bauxite for specific industrial uses, supported by reliable, long term supply chains from mine to end user.

Guinea – High Grade Bauxite

• Al₂O₃: 80-88%.
• Fe₂O₃: 2-4%.
• SiO₂: 4-8%.
• TiO₂: 3-4%.
• Moisture: < 1%.
• Size: 0–1 mm, 1–3 mm, 3–5 mm, 0–50 mm (custom sizing available).
