Despite hype, reprocessing of mine tailings is generally unlikely to yield economic production of critical minerals.
Shown here: global mine site sample data for antimony, gallium, lithium, and tin. Economic ranges in blue.
It’s rare for a single report to put an end to a bad policy idea, but I’m hopeful this tour de force from my colleague @PeterCookBTI does just that. Policymakers should not misinterpret mine tailings as a meaningful solution for critical minerals security. 🧵
