#294 The $3 Trillion Problem: Reindustrializing America’s Critical Mineral Supply | Nikhil Gupta (Determinant Materials)

Mining isn't the bottleneck for critical minerals—refining is. Traditional metal refining takes months and relies on toxic chemical processes, driving the supply chain straight to China. In this episode, Nikhil Gupta (Founder & CEO of Determinant Materials) reveals how his team uses advanced fluid dynamics to replace months of acid leaching with microparticle refining in mere minutes, slashing costs by 50% and bringing critical supply chains back home. 🔥 Enjoying Climate Cowboys?

In This Episode, We Cover: The Hidden Bottleneck: Why critical mineral security isn't about mining—it’s about processing. Months to Minutes: How Determinant Materials uses microparticle refining to separate metals at a macro scale. Geopolitics & National Security: China’s tungsten export bans, supply chain dominance, and why U.S. economic sovereignty depends on modular onshore refining. Reindustrializing America: Dropping modular refining units directly onto mine sites and defense primes. Key Episode Quotes: "Typical metal refining breaks materials down to the atom layer... We have a microparticle technology where we’re separating things at a bigger macro scale." "China banned the export of tungsten and the price went 10x overnight. China holds all that market power... To have real sovereignty, we need to have this processing here in the United States."
