Mining company South32 reported alumina production of 5.269 million tonnes in FY20, compared to 5.050 million tonnes in FY19, up 4 per cent year-on-year. In Q4 FY20, alumina production stood at 1.358 million tonnes, an increase of 6 per cent quarter-on-quarter.

Brazil Alumina saleable production increased by 10% to a record 1.383 million tonnes in FY20 as the refinery achieved improved performance in steam generation, enabling the benefits of the De-bottlenecking Phase One project to be realised.
“The company’s use of third party bauxite is expected to reduce in FY21, which together with a reset in the cost of supply from Mineração Rio do Norte S.A (MRN), in accordance with its linkage to alumina and aluminium, is expected to result in lower Operating unit costs for the refinery.”
Worsley Alumina saleable production increased by 2% to 3.886 million tonne in FY20, as the refinery finished the year on a strong note with an increase in calciner availability underpinning a 9% increase in production during the June 2020 quarter.
“The refinery continues to benefit from improvement initiatives that are expected to support a sustainable increase in production to nameplate capacity of 4.6Mt (100% basis).”
Sales increased by 20% during the June 2020 quarter as a result of higher production and a slipped shipment from the prior quarter.
