🌐 **INNOVATION BRIEF #4** | Turning Lithium Waste Into Rare Metals 🌐
China has unveiled the world's first 17-tower system to recover rubidium and cesium from lithium-processing waste — metals once too costly to extract and typically discarded as slag.
Key highlights:
- Launched by the Institute of Process Engineering (Chinese Academy of Sciences) with Ganfeng Lithium in Jiangxi
- 500-tonne-per-year production capacity
- 17 extraction towers replace a process that previously needed 70+ conventional tanks
By recovering these rare metals domestically, the breakthrough could strengthen supply chains for quantum networks, advanced batteries, and next-gen solar cells — showing that the future of mining may be about extracting more value from waste we already have, not just finding new resources.
