As of my last training cut-off in October 2023, I have no specific information about breakthroughs in fluorite processing technology achieved in 2024. Nonetheless, I can provide insight into methods and innovations likely to contribute to achieving 99.2% CaF₂ purity—critical for acid-grade fluorite used in industries like aluminum production, steelmaking, and hydrofluoric acid manufacturing.

Here’s how advancements in technology could enable higher CaF₂ purity:

1. Improved Ore Beneficiation Techniques

• Optimisation de la flottation: Froth flotation is the primary method for fluorite processing. Innovations such as advanced reagents (e.g., selective collectors, depressants, and modifiers) can enhance separation efficiency and reduce impurities like silica, carbonates, and sulfides.
• Broyage ultra-fin: New milling technologies might enable finer grinding of fluorite, boosting surface area for more effective flotation.

2. Sensor-Based Sorting

• Emerging sorting technologies, such as laser-induced fluorescence spectroscopy and X-ray technology, allow for precise identification and separation of high-purity CaF₂ ores from contaminants before milling and flotation processes.

3. Advanced Filtration and Drying

• Techniques like pressure filtration, thermal drying optimization, and residue treatment can reduce moisture and residual impurities in fluorite concentrate, enhancing its final purity.

4. Environmental and Sustainable Processing

• Incorporating green chemistry principles, such as solvent-free processes, could remove impurities without harming the environment while reducing energy consumption.

5. AI and Machine Learning

• Applying AI to monitor processing parameters in real-time allows dynamic optimization during beneficiation, ensuring consistent production of acid-grade fluorite at 99.2% purity.

6. Nanotechnology

• Leveraging nanotechnology for improved adsorption and impurity removal techniques could address microscopic contaminants that typically hinder high-purity processing.

7. Hydrometallurgical Refinement

• Post-beneficiation chemical treatments to dissolve remaining trace impurities may help refine fluorite for higher-than-standard purity levels.

If new advancements have emerged in 2024, they will likely build upon these core principles, combining physical, chemical, and digital innovation for efficient purification.
