Acid Grade Fluorspar Concentrate CaF₂ ≥97% (Main ≥97.5%) | Low Impurity & High Reactivity for HF Production
2. Product Introduction
This product is acid grade fluorspar concentrate, the core raw material for hydrofluoric acid (HF) and the fluorine chemical industry chain. Made from high-grade fluorspar ore through flotation, purification, drying and other processes, the CaF₂ content is stably ≥97%, with mainstream batches reaching over 97.5%. Impurities such as SiO₂, S, P and As are strictly controlled, and the -200 mesh passing rate is ≥90%. The powder features excellent fluidity and reactivity, making it the preferred industrial raw material for HF production, fluorine salt synthesis and fine fluorochemical manufacturing. It is suitable for continuous production in large chemical plants and supports stable long-term foreign trade supply.
3. Core Advantages
High Purity & Low Impurity, Tailored for High-End Fluorochemical Processes
With CaF₂ content ≥97% (main ≥97.5%) and strict control over impurities: SiO₂ ≤1.0%, S ≤0.05%, P ≤0.03%, As ≤0.01%, it effectively avoids by-product formation, equipment corrosion and product contamination. It guarantees the purity and quality of hydrofluoric acid and downstream fluorides, meeting the stringent raw material requirements of high-end fluorochemical production lines.
Fine & Uniform Particle Size for Stable, Efficient Reactions
With a -200 mesh passing rate of ≥90%, the powder has uniform particles and a large specific surface area. It ensures full contact with sulfuric acid and a stable reaction rate, significantly improving HF yield and reducing acid and energy consumption. The powder flows well and resists caking, perfectly matching automatic batching and continuous reaction equipment to keep production processes stable and controllable.

5. FAQ
Q1: What is the core difference between acid grade fluorspar concentrate and metallurgical/building grade fluorspar?
A: Acid grade fluorspar concentrate is defined by its high CaF₂ content and ultra-low impurities, specifically designed for hydrofluoric acid and fluorochemical production. In contrast, metallurgical and building grades have lower CaF₂ content and looser impurity controls, which cannot meet the strict purity requirements of the fluorochemical industry.
Q2: What are the practical advantages of the ≥97.5% CaF₂ mainstream specification for HF production?
A: Higher CaF₂ content means more active ingredient per unit of raw material, directly improving HF yield. It also reduces interference from impurities, minimizing side reactions and equipment wear. Long-term use can significantly lower overall production costs.
Q3: How does the -200 mesh ≥90% particle size affect fluorochemical production?
A: This standard ensures sufficient contact area between the powder and sulfuric acid, guaranteeing complete and stable reactions. It avoids incomplete reactions caused by oversized particles, or dusting and caking issues from overly fine powder, meeting the process requirements of most HF production lines.
Q4: Are the impurity levels compliant with industry standards?
A: All indicators are strictly controlled according to acid grade fluorspar industry standards. Harmful impurities such as SiO₂, S, P and As are kept below specified limits, effectively mitigating risks like equipment corrosion and insufficient product purity.
Q5: Can you provide stable long-term supply of acid grade fluorspar concentrate?
A: With stable ore sources and standardized flotation production lines, we maintain year-round mass production. Batch-to-batch consistency is ensured, supporting long-term foreign trade contracts and full container exports to meet the continuous production needs of overseas customers.
