The Situation

The Companhia Brasiliera de Aluminio (CBA) refinery is a 1 Mtpa alumina refinery located in São Paulo state in  Brazil. It processes bauxite from the neighbouring states of Minas Gerais and Goias and feeds the aluminium smelters adjacent to the refinery.

Scope

The scope of work was to identify opportunities to enhance refinery performance through process improvement initiatives.

Our Solution

Advisian undertook a flowsheet review for CBA at the end of 2011, which produced a prioritized list including twelve improvement opportunity recommendations.  

As at end 2015, two of these opportunities had been fully implemented and were delivering significant cash cost reduction, with return on investment approximately one month after implementation via increased production capacity, reduced bauxite consumption and improved energy efficiency. At that time, CBA were in the process of implementing another two of the original twelve recommendations.
