Alufer Mining operates the Bel Air bauxite mine in Guinea. Alufer discovered the deposit through maiden drilling in 2011 and took it all the way through feasibility, financing and construction, achieving first production on time, within budget and with zero lost time injuries in Q3 2018. The ramp up phase which followed commissioning progressed smoothly and the mine reached commercial production within the first six months of operation.
Bauxite mining at Hydro Paragominas (Pará) started in 2007 and today it employs about 1,500 permanent employees and about 600 workers on long-term contracts.
Hydro Alunorte is the world’s largest alumina refinery and has nearly 1,900 permanent employees and about 800 long-term contractors. Production at Hydro Alunorte started in 1995 and after three expansions now has a total capacity of over six million metric tonnes.
Managing dust emissions at Rio Tinto is a major focus during the dry season. Dust emissions from operations in Weipa, combined with windy conditions and the smoke that is often present from natural bushfires in the region, can adversely impact air quality for the local community.
