Bauxite residue is produced from the smelting of bauxite into alumina and this by-product is a large and growing global management problem for alumina refineries. Our research partners, an alumina refinery and an academic institution are assisting Alumtek Minerals with technical development. The success of the outcomes of this work will result in a long-term liability (bauxite residue) becoming a valuable resource, contributing to the circular economy and having a beneficial environmental outcome.

The Alumtek Minerals technical development has successfully demonstrated, in a 2 year research and development program recoveries of:

• Titanium
• Vanadium
• Iron oxide
• Aluminium hydroxide
• Supplementary Cementitious Material (SCM)

The recovery of the above products recycle 100% of the bauxite residue feed material.

Our goal now is to build a pilot plant from processes developed in the laboratory, leading to commercial operations.
