Australian Calcined Bauxite Fines
Australian calcined bauxite fines (<4.75mm) are fine-grained concentrates from rotary kiln calcination, applied in precision castables and anti-corrosion coatings. Classified as HTS 2606.00.0060 other calcined bauxite due to particle size and processing. Low silica content enhances purity for specialty refractories.

Calcined Bauxite for Aluminum Smelting
Calcined bauxite is a processed form of bauxite ore heated to remove moisture and impurities, resulting in a high-alumina concentrate used primarily as feedstock in aluminum production via the Bayer process. This product falls under HTS 2606.00.0060 as 'other' calcined bauxite, distinct from crushed or ground variants. It is graded for its alumina content, typically exceeding 50%.
High-Fracture Calcined Bauxite Aggregate
High-fracture calcined bauxite features angular particles with superior toughness, ideal for skid-resistant road surfacing and anti-slip pavements. Classified under HTS 2606.00.0060 as other calcined bauxite, it meets specifications for aggregate with high alumina content post-calcination. Its thermal processing enhances durability for abrasive applications.
Refractory-Grade Calcined Bauxite
Refractory-grade calcined bauxite is thermally treated to achieve over 85% alumina content, used in high-temperature furnace linings and kiln furniture. It is categorized under HTS 2606.00.0060 for other calcined bauxite concentrates. The calcination process densifies the ore for superior heat resistance.
Guyana Calcined Bauxite Lumps
Guyana-sourced calcined bauxite lumps are roasted bauxite ore in lump form (typically 25-150mm), used for proppants in oil fracking or as metallurgical flux. This falls under HTS 2606.00.0060 as other calcined bauxite, excluding fines or powder. High iron and titania content suits specific industrial blends.
