Bauxite Ore – Metallurgical Grade

Metallurgical Grade Bauxite sourced from reliable mines with stable alumina content, controlled impurities, and consistent sizing. Optimised for alumina refineries requiring predictable digestion behaviour, high extraction efficiency, and full traceability from mine to shipment.

Product Description

Bauxite is the primary ore used for aluminium production and forms the foundation of the Bayer refining process. At SGT, we supply high-quality Metallurgical Grade Bauxite sourced from trusted mining operations known for stable alumina content, controlled impurity levels, and consistent particle sizing. Our bauxite is specifically optimised for alumina refineries that depend on reliable feedstock to achieve high extraction efficiency, predictable digestion behaviour, and reduced red-mud generation.

Metallurgical bauxite is essential for producing smelter-grade alumina, which is further refined into primary aluminium through electrolysis. Beyond its core role in aluminium manufacturing, our bauxite also supports key non-metallurgical industries including cement, refractories, abrasives, and chemical processing.

SGT’s trading model ensures end-users receive material that meets strict quality standards, maintains full traceability, and consistently performs across various refinery conditions. With a robust sourcing network and efficient high-seas trading capabilities, we deliver bauxite that aligns with operational requirements for reactivity, mineralogical composition, moisture control, and overall process efficiency.

Typical Technical Parameters

  • Al₂O₃: 46–47%
  • SiO₂: 4%
  • Rejection: >4%
  • Fe₂O₃: 25%
  • Moisture: Maximum 10%
  • Particle Size Distribution:
    • 0–100 mm: 95% minimum
    • 100–200 mm: Maximum 5%

These specifications support stable digestion rates, optimized caustic consumption, and consistent refinery throughput, making our bauxite suitable for high-efficiency alumina extraction.
