Enhancing Magnetic Contrast through Mineral Phase Transformation: Flotation Performance of Bastnaesite-Transformed Products.

With resource depletion, the integrated utilization of low-grade rare-earth ores has garnered widespread focus. However, conventional beneficiation processes are unable to efficiently recover valuable components. This study provides a mineral phase transformation (MPT) strategy to enhance separation by amplifying the magnetic contrast between bastnaesite and iron minerals.

A Highly-Fluorinated Lithium Borate Main Salt Empowering Stable Lithium Metal Batteries.

Traditional lithium salts are difficult to meet practical application demand of lithium metal batteries (LMBs) under high voltages and temperatures. LiPF, as the most commonly used lithium salt, still suffers from notorious moisture sensitivity and inferior thermal stability under those conditions. Here, we synthesize a lithium salt of lithium perfluoropinacolatoborate (LiFPB) comprising highly-fluorinated and borate functional groups to address the above issues.
