China's fluorspar (fluorite) industry has transitioned from resource extraction to deep processing alongside the development of fluorine chemicals and high-end manufacturing. In the 1980s and 1990s, relying on abundant fluorspar resources in Zhejiang, Inner Mongolia, and other regions, the industry focused on mining and primary processing. Products were mostly acid-grade fluorspar powder (CaF₂ content ≥97%), mainly used in basic applications like metallurgical flux and primary fluoride production, resulting in low resource utilization and limited added value. Since the turn of the century, the upgrading of the fluorine chemical industry (fluorinated refrigerants, fluorinated polymers) and stricter environmental policies have driven the industry's transformation toward purification, deep processing, and functional applications. Through processes such as flotation and gravity separation, high purity (CaF₂ content ≥99.5%) has been achieved, leading to the development of optical-grade and electronic-grade fluorspar products. Downstream derivatives such as hydrogen fluoride (HF) and various fluoride salts have also emerged, enabling breakthroughs in high-end fields like new energy, optics, and semiconductors.

In recent years, high-end demand for lithium battery electrolyte components (e.g., lithium hexafluorophosphate, LiPF₆) and optical-grade fluorspar crystals has surged. Coupled with the evolution of related standards, the industry is accelerating its upgrade toward resource efficiency and high-end products. Today, China is the world's largest producer and consumer of fluorspar, with products covering the full spectrum: raw ore (lump), fluorspar powder, fluorspar crystals, and fluorine chemical intermediates. These are widely used in dozens of fields, including fluorine chemicals, metallurgy, optical instruments, and new energy.

We have set up a dedicated fluorine mineral testing team. Based on product type and application scenario (feedstock for fluorine chemicals, optical components, metallurgical flux), we provide customized testing services—including purity analysis, impurity detection (e.g., silica, calcium, sulfur compounds), optical performance, and chemical reactivity—helping products build advantages in performance optimization and compliance.
