Why KCL Density Measurement Matters in Flotation
KCL flotation is a delicate process where crude salt (KCl and NaCl) is mixed with saturated mother liquor, ground to ~1mm crystal size, and processed in flotation cells. Surface-active reagents coat KCL crystals, enabling air bubbles to form a KCL-rich foam, while NaCl sediments for further processing. Accurate KCL density measurement ensures optimal slurry concentration, which is pivotal for reagent efficiency, foam stability, and effective separation.
Compromised Reagent Efficiency: High slurry densities (>1.3 g/cm³) increases viscosity, hindering amine dispersion and reducing bubble attachment efficiency by 10-15%, lowering KCL recovery to 80-85%. Low density (<1.1 g/cm³) dilutes reagents, increasing amine consumption by 20-30% and risking KCL loss in tailings (up to 5% KCl content).
Foam Instability: Excessive density creates viscous “dead foam” with low froth mobility, entraining impurities like NaCl or MgSO₄ (up to 5-7% contamination), reducing KCL purity to <95%. Low density produces thin, unstable foam, allowing fine KCL particles (<0.1mm) to escape, cutting yields by 5-10%.
Equipment Stress: High-density slurries increase shear forces on flotation cell impellers, reducing lifespan by 20-30% (e.g., 6-9 months vs. 12 months). Low-density slurries elevate water usage in dewatering (e.g., 1.5-2 m³/ton KCl), raising energy costs by 15-25% during centrifugation.
Process Variability: Manual density sampling, with 10-30 minute delays, causes fluctuations (±0.05 g/cm³), disrupting froth stability and recovery consistency, increasing operator workload by 25%.
