Alumtek Minerals (AM), based in Australia, recently completed research and development on bauxite residue waste, commonly known as red mud, which has resulted in the development of a technology to extract critical raw materials. Following a collaboration with Cement Australia, AM developed a supplementary cementitious material (SCM) that meets the stringent Australian Standard AS3582.4 and has the potential to substantially reduce CO2 emissions.

US aluminium producer Alcoa has partnered with Brisbane-based Alumtek Minerals, the developer of a process to extract critical minerals including gallium, vanadium, hafnium and rare earths from mining waste.

Alumtek Minerals is pleased to have been awarded a CRC-P grant from the Australian Government. This Project will further develop and commercialise existing proprietary processing technology (developed by Alumtek Minerals over the last three years) to extract critical minerals and rare earths from bauxite residue. This industry-led project, a partnership between Alumtek Minerals, Alcoa and Chemistry Centre WA, will deliver a comprehensive test work program, building on previous positive proof-of-concept results, which will produce initial quantities of various critical minerals and rare earth elements.

SGS Metallurgy has completed a six-month testing and optimisation program of Alumtek Minerals’ proprietary technical process. The purpose of the program was to further optimise the extraction of critical minerals from bauxite residue as well as to “close the loop” on the process as much as possible i.e., to also maximise the extraction of saleable by-products and to render the subsequent residue – Activated Bauxite – suitable for beneficial re-use. The testing program was highly successful. This process, known as AM Process No. 17, has confirmed the ability to produce commercial quantities of hafnium, lithium, niobium, scandium, titanium, vanadium, zirconium, along with saleable by-products and neutralised, re-useable waste in the form of Activated Bauxite.
