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 included an alumina refinery and an academic institution. 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 3year R&D program recoveries of:
- Titanium
- Vanadium
- Gallium (oxide)
- Iron oxide
- Aluminium hydroxide
- Supplementary Cementitious Material (SCM)
- Geopolymer binder.
The recovery of the above products recycle 100% of the bauxite residue feed material. AM cementitious materials (SCM & geopolymer binder) play a significant role in reducing greenhouse gas emissions.
AM is actively seeking partnerships with interested parties to advance our technology even further.
