The flotation simulator was calibrated and tested using three industrial data sets from concentrator plants in Chile (Circuits 1, 2 and 3), as shown in Table 1.The flotation rate constants and the maximum recoveries per size-by-liberation class were adjusted in each case.
The StackCell, which is much smaller than a traditional flotation cell, can shrink the size of a flotation plant by 50%. The knock-on effect is that it also requires less concrete (smaller carbon footprint), less piping to connect the units, and fewer electrical connections and cable trays and pipe racks, thus reducing CAPEX and engineering ...

In this study, the Telfer flotation and CIL plant was chosen as a case study, representing a copper–gold ore with a significant iron sulphide content. This plant currently operates at 21 Mtpa ore throughput and recovers gold by gravity separation, copper flotation and CIL. The feed grade is about 0.18% Cu and 0.7 g/t Au.
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 …
