Geomega Announces Progress on Innovative Bauxite Valorization
Revolutionizing Bauxite Residue Valorization
Geomega Resources Inc. (“Geomega” or the “Corporation”) (TSX.V: GMA) has made significant strides in its bauxite residue valorization activities in collaboration with Rio Tinto. This initiative represents a pivotal step towards sustainable practices in the aluminum industry.
Overview of the Pilot Project
The pilot project, launched in early 2022, aims to address the challenges posed by bauxite residue—a byproduct of aluminum production—by developing innovative recycling technologies. Geomega's approach is multifaceted, incorporating three distinct circuits designed to optimize the extraction and valorization of valuable materials contained in bauxite residues.
Circuit 1: Alkalinity Removal and Product Production
Circuit 1 is dedicated to the removal of alkalinity while generating several key byproducts including sodium, calcium, aluminum, and silica products. This first phase of processing significantly reduces waste volume by 10% to 30%, laying the groundwork for subsequent circuits.
Circuit 2: Iron Extraction
Circuit 2 targets iron extraction, producing valuable Direct Reduced Iron (DRI) with high purity. The combination of Circuits 1 and 2 contributes to a remarkable waste volume reduction over 70%, further emphasizing the efficiency of Geomega's technology.
Circuit 3: Rare Earth Elements and More
Circuit 3 focuses on extracting high-value rare earth elements (REEs) and titanium concentrates from the remaining materials. This circuit also prioritizes reagent recycling, resulting in minimal effluents and a lower environmental footprint. Potential products include scandium, gallium, alumina, and silica, showcasing the broad spectrum of resources obtainable through this innovative process.
Validation and Future Steps
The past three years have seen Geomega conduct extensive testing, leading to successful validation of the key process parameters and achieving collaboration milestones with Rio Tinto. Pilot testing for the initial two circuits has yielded representative samples crucial for the upcoming pilot of Circuit 3, scheduled for 2025.
With the signing of an extension to their agreement, Geomega and Rio Tinto are poised to continue exploring the possibilities of Circuit 3. Plans for advancing Circuits 1 and 2 are also in the works, driven by positive preliminary results. These upcoming phases promise to bring further clarity and direction as an agreement is finalized.
Industry Impact and Leadership Comments
Kiril Mugerman, President & CEO of Geomega, expressed pride in the remarkable journey of their bauxite residue valorization technology, commending the team for its successful transition from bench to pilot scale operations. He emphasized the importance of such technology in addressing the aluminum industry's environmental impact while meeting the demand for critical metals necessary for modern technology.
On the partnership front, Josette Ross, General Manager of Rio Tinto’s Arvida Research and Development Center, highlighted the role of research collaborations in enhancing sustainability within aluminum production. She expressed her enthusiasm for the promising results of their joint efforts.
