Flotation plants operate in increasingly challenging environments where multiple cross-correlated variables need to be understood and managed at every level. Variable feed characteristics such as feed grades, liberation, particle size distribution, and minerology present challenges for flotation process control and stability, ultimately ...

The aim of this study is to diagnose and optimize a closed multistage gold ore flotation circuit in an operational industrial plant. Linear circuit analysis (LCA), a partition-based model, and a mass balance model using flotation first-order kinetics are employed to diagnose the current process. The result shows that the current circuit operates with high recovery but the …

Additionally, BBD and ANOVA analysis revealed that flotation time, pulp pH, and ester dosage significantly influenced P 2 O 5 grade and recovery, while amine dosage had a less pronounced effect. RSM optimization yielded optimum flotation conditions of 10 minutes flotation time, 481.81 g/T ester dosage, 400 g/T amine dosage, and 4.58 pulp pH.
