Dr Richmond K. Asamoah is an internationally recognised researcher in mineral processing, extractive metallurgy, resource recovery, and data-driven process optimisation. His work sits at the intersection of mineral engineering, surface and interfacial science, sensing technologies, and artificial intelligence, with a strong focus on developing sustainable solutions for the future resources sector. Through close collaboration with industry, government and academia, he is helping transform how complex ores, mine wastes and critical mineral resources are characterised, processed and valorised to support the global energy transition.
Richmond holds a BSc (Hons) in Minerals Engineering from the University of Mines and Technology (Ghana) and a PhD in Minerals and Resources Engineering from the University of South Australia. Over the past fifteen years, he has built an extensive track record spanning fundamental research, industrial problem-solving and technology development across mineral processing, hydrometallurgy (including bio), process mineralogy, flotation chemistry, critical minerals, sensing technologies, machine learning and data-driven process optimisation.

Research Vision

The mining industry faces a defining challenge: how to recover more value from increasingly complex, lower-grade and environmentally sensitive resources while reducing energy, water and carbon footprints. Richmond's research addresses this challenge by integrating advanced sensing, process intelligence and innovative extraction technologies to create the next generation of resource recovery systems.

His research program is built around three interconnected themes:

  • Smart sensing and process intelligence, utilising machine learning, acoustic sensing, real-time monitoring and data analytics to improve mineral processing performance and decision-making.

  • Sustainable extraction and beneficiation of precious metals and critical minerals, including battery materials, rare earth elements, nickel, cobalt, copper and gold from both primary ores and secondary waste streams.

  • Resource efficiency and circular economy solutions, focused on unlocking value from low-grade resources, tailings and industrial wastes through innovative and environmentally responsible processing routes.

A distinguishing feature of his work is the combination of fundamental mineral science with practical industrial implementation, ensuring that research outcomes can be translated into measurable operational improvements and sustainable resource development.

Research Excellence and Impact

Richmond has established an international reputation through contributions to flotation chemistry, coarse particle recovery, refractory gold processing, hydrometallurgy, process optimisation and machine-learning applications in minerals engineering. His research has generated new understanding of the behaviour of complex mineral systems and provided innovative solutions for improving recovery, selectivity and process efficiency.

His publications span leading journals in the minerals processing field including Minerals Engineering, Hydrometallurgy, Powder Technology, Chemical Engineering Research and Design, Journal of Hazardous Materials and Advanced Powder Technology, attracting and reflecting sustained international recognition and influence.

Recent research contributions include machine-learning models for flotation prediction and optimisation, acoustic sensing systems for AG/SAG milling operations, recovery of critical minerals from complex laterite and waste resources, and innovative approaches to coarse particle flotation and resource upgrading. 

Leadership, Collaboration and Industry Engagement

Richmond leads the Asamoah Research Lab, a multidisciplinary team focused on pioneering processing solutions for the mineral resources sector. The laboratory combines advanced characterisation, smart sensing, data science and metallurgical engineering to create next-generation technologies for sustainable resource utilisation. 

Recent contributions to nationally and internationally significant research initiatives include the Australia–India Strategic Research Fund (AISRF) and the Premier's Research and Industry Fund Research Consortia Program (PRIF-RCP), where he is advancing technologies for critical minerals recovery and lean processing of complex resources. He also serves as an Associate Investigator within the ARC Centre of Excellence for Enabling Eco-Efficient Beneficiation of Minerals.

Throughout his career, he has worked closely with mining companies, technology providers, government agencies and research organisations to address practical operational challenges. His expertise is regularly sought by industry partners seeking innovative solutions in mineral processing, metallurgy and resource recovery. He has also supported South Australian small and medium enterprises through the Future Industries Accelerator, helping businesses solve critical technical and operational challenges.

Richmond is a Chartered Fellow of the Australasian Institute of Mining and Metallurgy (AusIMM) and actively contributes to professional and research communities, including the Institution of Chemical Engineers (IChemE).

Research Training and Future Directions

As a supervisor of Higher Degree by Research students, Richmond is committed to developing the next generation of engineers, metallurgists and research scientists. His mentoring philosophy emphasises scientific excellence, interdisciplinary thinking, innovation and real-world impact.

Looking ahead, his research aims to accelerate the digital transformation of mineral processing through artificial intelligence, sensing technologies and predictive analytics while advancing sustainable resource engineering.
