Froth properties and entrainment in lab-scale

2019-2-1  The lab-scale batch flotation of high-grade apatite ore leads to significant changes of pulp properties (Fig. 11, Fig. 12(a)) and froth properties (froth structure and froth stability) with time. These changes are caused by the high mass pull which goes along with decreasing reagent and particle concentrations during the lab-scale flotation.
