ActiveFluorspas—Determination of particle size distribution by sieving
萤石 粒度的筛分测定
Application Summary AI generated
This standard specifies the sieving method for determining the particle size distribution of fluorspar (fluorite) ores and concentrates. It is applied in the mining and mineral processing industry for quality control during production, trading, and use of fluorspar, particularly for metallurgical, chemical, and ceramic applications where particle size affects smelting efficiency or chemical reactivity. The method covers dry or wet sieving procedures using standardized test sieves to classify particles from coarse lumps to fine powders.
