Results from this work indicate that high-grade bauxite is present with available alumina – the portion of Ai2O3 that can be extracted under Bayer process conditions – exceeding 34.5% and ...

Results from this study confirm the presence of high-grade bauxite, with available alumina (extractable under Bayer process conditions) exceeding 34.5% and reactive silica measuring 3.14%.

Alumina refining relies on a process known as the Bayer circuit, or Bayer Process, which requires heat in the form of steam to extract and refine alumina from bauxite.

The Bayer process, invented by Austrian chemist Karl Josef Bayer in 1888, is widely used to refine bauxite into smelting-grade alumina, or aluminium oxide – the precursor to aluminium.

China is a top aluminium producer and consumer but it lacks the high-quality bauxite needed to make it. The country instead relies on imported aluminium ore from Guinea and Australia – but that ...
