文摘

The effect of negative inertial force on flotation rate constant was investigated. The GSE and Schulze collision models were compared through flotation rate constant. Effect of mineral density on flotation rate constant models was investigated. Neglecting negative inertial forces conduces inaccuracy in flotation rate constant. GSE and Schulze collision models exhibited agreement only at fine particle sizes.
