Desensitized Case / Fluorite
Plant trial on a high-silica low-grade fluorite ore
With grinding, flotation flowsheet, major equipment and operating practice essentially unchanged, the collector scheme was switched from conventional oleic acid to HBYS-1 fluorite collector and continuous plant indicators were tracked.
Trial Background
Evaluating plant response through shift-by-shift data
The feed was dominated by SiO2 and CaF2, with high silica content and low CaF2 grade. The plant operated a flowsheet of one roughing stage, six cleaning stages and four scavenging stages. The comparison base used six shifts over three days under conventional oleic acid; the HBYS-1 period tracked twelve continuous shifts.
Maintained and slightly improved at lower dosage
Lower fluorite loss in tailings
More stable continuous operation
Improved impurity indicators
Average CaCO3 decreased from 1.02% to 0.88%, and average SiO2 decreased from 1.54% to 1.48%.
Stable flowsheet conditions
Grinding, flotation circuit, main equipment and operating practice were essentially unchanged during the trial.
Traceable results
Conclusions are based on continuous shift statistics, suitable for judging reagent adaptability in the existing plant system.
