Why this matters
Fluorspar is the commercial name for fluorite, a calcium fluoride mineral used as a feedstock and flux. Buyers usually start with CaF2, but the practical buying question is whether the whole impurity and handling profile fits the plant.
CaF2 is the first filter, but impurity levels, moisture, and the physical form determine whether the cargo is actually useful in a plant or furnace.
Buyer checklist
If you are using this article for RFQ prep, these are the details that should be explicit before a supplier quote is meaningful.
- Ask for CaF2, SiO2, CaCO3, sulphur, phosphorus, and moisture on the same COA.
- Confirm whether the material will be used as powder, lumps, or briquettes.
- Match the grade to the buyer process before comparing price.
Common mistakes
These mistakes slow down procurement or create quality surprises after the cargo lands.
- Buying by grade name alone and ignoring impurity limits.
- Assuming all fluorspar behaves the same in a chemical or metallurgical process.
- Treating the shipment form as an afterthought.
Practical takeaway
A good fluorspar spec is a complete buying profile, not just a purity number.
