Industry Expert FAQ: Bauxite Specifications

What determines refractory quality in bauxite?

The alumina-to-silica ratio (A/S ratio) is critical. Premium refractory-grade bauxite requires A/S ratio above 12:1 with controlled iron content to ensure high refractoriness under load conditions. Additional calcination transforms mineral structures for thermal stability.

What particle sizes do first bauxite suppliers deliver?

Standard sizing includes:

  • 0-1mm for binder applications
  • 1-3mm for tundish mixes
  • 3-5mm for castable aggregates
  • Custom sizing to 200 mesh

What calcination methods exist?

Rotary kilns (1500°C) achieve 1-3% LOI for refractories while shaft kilns (1200°C) produce medium-calcined ore for abrasives. Hydration resistance tests validate proper crystal transformation.

How do XRD tests verify quality?

X-ray diffraction identifies mineral phases post-calcination. Premium bauxite should show corundum as the dominant phase with minimal mullite. Gibbsite presence indicates incomplete calcination.

What are major processing contaminants?

Common impurities include quartz (SiO₂), hematite (Fe₂O₃), kaolinite clay, and titanium oxides. Beneficiation processes reduce these to required specifications.

How do bulk densities vary?

True density ranges 3.0-3.6 g/cm³ while apparent porosity of calcined bauxite falls between 3-12%. Industrial standards require minimum bulk densities of 2.8 g/cm³ for refractory aggregates.

What packaging standards exist?

1-ton super sacks with UV protection are standard for bulk shipment. Custom packaging available including 25kg laminated bags, big bags on pallets, or bulk vessel shipments exceeding 20,000 tons.

Global Supply Chain Considerations

Leading first bauxite exporters must maintain:

  • Strict chemical and physical specifications across shipments
  • Advanced processing technology ensuring consistency
  • Strategic inventory management
  • Customized logistics solutions
  • Responsible mining certifications (ISO, OHSAS)

"The increasing demand for high-alumina refractories is transforming bauxite specifications. Suppliers offering consistent chemistry with advanced processing infrastructure will dominate future markets." - Refractories World Forum
