Abstract

Abstract

En 中文
• Gangue recovery in the JKHFmini is dominated by hydraulic elutriation rather than flotation. • Elevated air and water fluxes significantly increase gangue carryover and mass recovery. • Gangue elutriation is time‑dependent, with selectivity deteriorating beyond ∼ 4 min. • A predictive relationship links gangue cut size (d50c) to air and water velocities.
