SnapshotThe Juruti bauxite mine represents an established mining operation which includes:
- Bauxite beneficiation plant for ore crushing and washing;
- Mine waste facilities including tailings thickening lagoons and tailings disposal ponds.

Alcoa has invested in a new fleet of vessels for transporting bauxite between the Juruti mine and the Alumar port in the state of Maranhão, which will help reduce transportation costs and lower greenhouse gas emissions. However, current issues with the waterway may affect the effectiveness of these initiatives.

On November 6, 2024, Alcoa declared force majeure on bauxite shipments from the Juruti mine due to a vessel stuck in the Juruti port channel. This situation has led to a halt in cargo shipments that has been ongoing since the end of October. This incident has become an additional factor contributing to the rise in prices for aluminum and alumina ore on global markets.

Alcoa World Alumina and Chemicals (AWAC) is an unincorporated global joint venture between Alcoa Corporation and Alumina Limited. Alcoa provides the operating management for AWAC. AWAC entities' assets include the 100% interests of the Juruti bauxite deposit and mine in Brazil.

On August 1, 2024, Alcoa Corporation announced the successful completion of its acquisition of Alumina Limited (“Alumina”). Alcoa completed the acquisition of all ordinary shares of Alumina, through a wholly owned subsidiary, AAC Investments Australia 2 Pty Ltd.

With Alcoa’s acquisition of Alumina, the Alcoa World Alumina and Chemicals (AWAC) joint venture is now fully owned and controlled by Alcoa.

Deposit type

  • Laterite
  • Bauxite

Summary:

The bauxite deposit of the Juruti bauxite mine consist of several lateritic bauxite plateaus which exist over a large lateral extent (several km) in comparison to the total thickness of the deposit (typically up to 20 m below surface).

Juruti is a lateritic bauxite deposit formed through a combination of intense weathering and geochemical alteration, leaching by meteoric waters, and accumulationof alumina and iron-rich horizons. Periodic erosion and redeposition is also known to have occurred.

The lateritic deposits have originated from the Alter-do-Chao Formation; Cretaceous fluvial-lacustrine deposits of sandstone, siltstones, mudstones, and quartzbreccia. Weathering and alteration of these parent rocks is estimated to have taken place during the Eocene.

Bauxitization has occurred through the formation of gibbsite crystals which form massive bauxite horizons which exist as plateaus across the Juruti region. Incomparison to their lateral extent over tens of kilometers, the overall thickness of the bauxite deposits are relatively thin being only several metres thick.

Mineralization
Bauxite mineralization principally occurs as microcrystalline gibbsite (Al(OH)3), along with accessory minerals of hematite (Fe2O3), goethite (FeO(OH)), kaolinite (Al2Si2O5(OH)4),and anatase (TiO2). The mineralization of each of the stratigraphic horizons observed across the Juruti deposits are classified based on a combination of visual inspection during drilling and sampling, and the results of chemical analysis.
