How a Little Known Technology Can Break China’s Rare Earths Stranglehold | Dr. James Tour

Nov 22, 2025
Dr. James Tour, a synthetic chemist and nanotechnologist at Rice University, discusses revolutionary flash Joule heating technology that could free the U.S. from dependence on Chinese rare earth resources. He explains how this method extracts critical minerals from waste and mine tailings, emphasizing its environmental advantages and cost-effectiveness. Tour also outlines the potential for creating localized recycling plants and the strategic importance of these innovations for national security. This could reshape supply chains and bolster the economy.

INSIGHT

Flash Joule Heating Enables Rapid Metal Separation

  • Flash Joule Heating converts wastes into volatile metal chlorides by rapid resistive heating in chlorine gas.
  • This enables selective, fast separation of multiple metals without water or strong acids.
INSIGHT

Temperature Control Enables Sequential Recovery

  • Metal chlorides form and distill at much lower temperatures, allowing staged recovery by temperature control.
  • The process can separate one metal after another by tuning reaction and distillation temperatures.
ANECDOTE

General Says Tech Could Prevent Wars

  • A NATO general told Dr. Tour the tech could prevent wars by removing resource drivers for conflict.
  • The general said he wouldn't have to fight for rare metals if they could be produced from waste domestically.
