In this episode, we return to critical metals and how their fortunes are affected by the energy transition, technology and geopolitics. To tell that story we are focusing on three in particular: Neodymium, Gallium and Hafnium. Each has a key role in the modern world with demand set to grow but with challenges that markets and policy makers are grappling with. Speaking to Paul Chapman, our guest is Ellie Saklatvala, Head of Non-Ferrous Pricing at Argus Media, the leading independent pricing agency.
