Electro-based separation technology for critical mineral recovery

The global transition toward clean energy, digital technologies, and advanced manufacturing has led to a surging demand for critical minerals, such as lithium, cobalt, nickel, rare earth elements, and vanadium. These minerals are vital for applications ranging from electric vehicle batteries and solar panels to electronics and defense systems. However, conventional extraction methods are often energy intensive, inefficient, and dependent on complex supply chains. Leveraging the research capabilities of Deakin University (Australia) and the Indian Institute of Technology Madras (India), this collaborative project aims to develop an integrated electrochemical separation platform. The technological scope may encompass one or more of these methods: electrodialysis, electrowinning, electro-leaching, electro-membrane separation, electrochemical adsorption, and bipolar membrane electrodialysis for efficient, sustainable, and selective recovery of critical minerals from various sources, such as mining tailings, industrial waste streams, and end-of-life products.

Electro-based methods offer a compelling alternative to traditional hydrometallurgical and pyrometallurgical approaches. By using electricity to drive separation and purification processes, these technologies can provide precise control over reaction conditions, reduce chemical reagent use, and lower energy consumption. The core objectives of this project are to design novel electrochemical systems, improve selectivity and efficiency for target minerals, and assess the scalability and economic viability of these technologies for industrial deployment. Collaborations with industry partners will ensure that the research is aligned with real-world challenges and market needs, particularly in the Australian context, where the abundance of mineral resources and commitment to sustainable mining create unique opportunities.

The anticipated outcomes of the project include the development of next-generation electrochemical recovery systems, proof-of-concept demonstrations for key critical minerals, and a framework for integrating electro-based technologies into existing mining and recycling operations. This project will address a strategic need by pioneering sustainable electrochemical technologies for critical mineral recovery, bridging the gap between resource extraction and environmental stewardship while contributing to national and global goals in energy security and technological innovation.
