Australian researchers find carbonate melts dissolve and transport valuable 'green' metals from Earth's mantle.

Australian researchers have discovered how low-temperature, carbon-rich melts can bring valuable 'green' metals, essential for renewable energy technologies, from deep within Earth's interior mantle. The study, led by Macquarie University, showed that carbonate melts can dissolve and carry a range of critical metals and compounds, including nickel, copper, cobalt, gold, and silver, from surrounding rocks in the mantle. This new information may inform future metal prospecting efforts.
