Import Bauxite — Buy in wholesale FOB from Supplier in Brazil

Woca Company supplies metallurgical-grade bauxite ore from Brazil with minimum 53% Al2O3, maximum 8% SiO2, and maximum 7% Fe2O3, positioning it for alumina refineries and aluminium smelters. The specification sheet also caps CaO at 0.4%, TiO2 at 1%, and loss on ignition at 35%, with moisture held to 15% maximum, available alumina at 48% minimum. These parameters indicate a gibbsite-rich or mixed bauxite typical of Brazilian deposits, suited to low-to-medium temperature Bayer digestion.

Brazilian bauxite from the northern plateau regions, including Paragominas and Trombetas deposits, is generally recognised for its low reactive silica content and favourable mineralogy for alumina extraction. The 53% Al2O3 minimum places this offering in the mid-range of export grades, below the 55-60% typical of Australian or Guinean premium bauxite but competitive on freight differentials to Atlantic Basin and European refineries. The 8% SiO2 ceiling is workable for modern refineries with efficient desilication circuits, though buyers should distinguish between total silica and reactive silica in their technical due diligence.

This material is prepared in standard lump and sized gradings for bulk ocean freight, with strict LOI and moisture controls stated to preserve integrity during Atlantic transit. Primary end-users include alumina refineries in Europe, North America, and the Middle East, as well as traders serving integrated aluminium producers. The available alumina floor of 48% is the critical economic parameter for refinery yield calculations, and buyers should verify how this figure was determined, whether by the standard method (reacting with caustic at specified conditions) or by theoretical calculation from mineralogy.

Woca Company is located at Rua Doutor Cesar 1161 in Sao Paulo, Brazil, postal code 02013004. The company holds a harbor-level trust tier on the marketplace, though its response rate shows 0.00% with zero average response hours, indicating that direct communication testing is essential before procurement planning. Sao Paulo is a commercial and logistics hub rather than a mining centre, so buyers should clarify whether Woca Company operates as a trader, agent, or direct mine operator with processing facilities elsewhere in Brazil.

The listing does not disclose founding date, number of employees, annual turnover, mining concessions, or reference clients. What is presented is a detailed chemical specification with explicit maximums and minimums, suggesting technical familiarity with refinery buyer requirements. No historical narrative, workforce size, or client roster is invented here. Buyers should request the company's CADASTUR mining registration, environmental licences, and proof of port access agreements to validate operational substance.
