About Nuton

3 decades of R&D to unlock copper for the future

Nuton is a Rio Tinto venture founded on 30 years of research and development. Although our research is vast, our ambition has been focused from our beginning – producing better copper with a smaller environmental footprint.

A leader within the industry, Rio Tinto’s commitment to finding better ways to provide the materials the world needs backs everything we do. The first leaching tests that served as the foundation for our technologies were conducted at Bundoora in Melbourne, Australia, in 1996. After further development, Nuton launched as a corporate startup in 2021. We’re now working with several key partners to deliver lower footprint copper production, documented in ongoing, collaborative viability studies.

As we look to the future, we see opportunities to use the power of our technologies to help progress global decarbonisation.

Why Nuton?

We unlock value from hard to process ores and achieve copper recovery rates above industry benchmarks. Among primary copper sulphides, we can recover up to 85% of copper, well above traditional heap leach processes. Our technologies benefit a wide array of applications including brownfield and greenfield sites, waste rock and tailings, complex ores, and historic sites.

At Nuton, our ambition is to produce copper with the world’s lowest footprint and stretch ourselves to achieve Positive Impacts in at least one of our five pillars: water, materials, energy, land and society.
