New Podcast Explores the Future of Responsible Mining and Critical Minerals

The latest episode of the State of the Earth Podcast takes a closer look at one of the biggest challenges in the global transition to net zero: meeting rising demand for critical minerals while ensuring mining is responsible and sustainable.

Hosted by Sophie Crossley, the episode features Professor Frances Wall, a leading expert in critical minerals and sustainable resource development, recently awarded an OBE for her contributions to geoscience.

Together, they explore why critical minerals are essential for technologies such as electric vehicles, wind turbines, and renewable energy systems—and why scaling up supply must go hand-in-hand with improving environmental and social outcomes.

The discussion highlights what “responsible mining” really means in practice, from reducing environmental impact and emissions to building trust with communities. It also examines the growing importance of circular economy approaches, including recycling and reuse, to reduce pressure on primary resources.

A key focus is the challenge of mineral processing, often one of the most energy-intensive and complex parts of the value chain. Advancements in this area will be critical to delivering more sustainable outcomes.

The episode also explores Cornwall’s re-emergence as a centre for critical minerals, drawing on its rich mining heritage while supporting innovation in sustainable resource development.

Looking ahead, the conversation touches on the policies, technologies, and supply chain shifts likely to shape the industry in the coming years—and the steps needed to rebuild public confidence in mining as a key enabler of the net zero transition.
