Today, we discuss three critical minerals to illustrate, and challenge or reinforce the common narratives out there, the intractable problems those supply chains face - even with projected soaring future demand. And consequently, the influence these elements have on geopolitics and economics. Influence that is only growing. We're talking Yttrium, Rhenium and Graphite and each one tells a different story about our modern economy about the critical mineral supply chain and pricing and some of that challenges that poses to governments, companies and us as individuals. To tell those stories we are rejoined by Ellie Saklatvala, Head of Metals Pricing at the Independent Price Reporting Agency, Argus.
