Zhang et al. [26] performed hydroxide precipitation at 60 °C with NaOH solutions for removal and recovery of manganese(II) from synthetic laterite waste solution containing 2 g/L Mn 2+, 15 g/L Mg 2+ and 0.5 g/L Ca 2+ (Table 2).At pH 8.2, 71% precipitation of Mn 2+ occurred along with 5% Mg 2+ co-precipitation. At pH >9, the …

The flotation performance (e.g., grade, recovery, and kinetics) of RFC was reported superior to the conventional systems (Cole et al., 2020). Fast and efficient flotation in RFC can be achieved by maximizing the kinetics of particle–bubble attachment, the interfacial bubble flux for particle extraction, and the rate of bubble–liquid ...

However, a simultaneous removal (co-flotation) of Cd 2+, Zn 2+, and Mn 2+ has not been investigated yet either in chelated or in non-chelated flotation systems. Hence, the objective of this paper is to determine the optimum conditions for the co-flotation of Cd 2+, Zn 2+, and Mn 2+ in one step, from dilute aqueous synthetic …
