Earth

Chemistry is vital to Earth, shaping everything from the air we breathe to the water we drink. It explains the composition of rocks, fuels innovation, and sustains life through biological processes.

Michael Edmonds

Michael is a passionate science and education advocate, and augmented his PhD in organic chemistry (1995) with a Masters in organisational psychology (2023). His Master’s thesis focused on student/learner motivation and wellbeing.

Could New Zealand’s geothermal fields be mined for the rare earths?

Although the market for lithium and rare earth element metals is highly volatile, the compositions of geothermal fluids from New Zealand’s electricity-generating geothermal fluids appear potentially economic for lithium and possibly for rare earth elements (REE), providing a supplementary income stream to electricity production.
