Changsha Research Institute Advances Tungsten Recovery, Solid-State Electrolytes and Solar Recycling

Highlights

• CRIMM's Xianglushan Tungsten project processed over 200,000 tonnes of ore with tungsten recovery above 80% and copper recovery above 75%.
• A 100-ton-scale oxide solid-electrolyte pilot line achieved continuous automated production with ionic conductivity exceeding 1.0 mS/cm and 100% yield.
• A new photovoltaic recycling process recovers silver at ≥99% purity and ≥95% recovery rate from end-of-life solar panels.
• CRIMM's parent, China Minmetals, is building end-to-end critical materials technology from ore concentration through advanced materials to recycling.
• All performance claims originate from a Chinese state-owned enterprise and should be independently verified before use in investment or procurement decisions.
