Dual-chamber flotation machines are not new. Early forms of the modern dual-chamber pneumatic cells can be traced back to the early 1960s [].Their primary characteristic is that—unlike mechanical flotation cells where the gas-particle adhesion occurs in an agitated, aerated tank—most of the gas-particle adhesion takes place in a separate, high-intensity …

Abstract: In this work, the prediction and optimisation of copper flotation has been conducted in the rougher flotation circuit. The copper-recovery prediction involved the application of support vector machine (SVM), Gaussian process regression (GPR), multi-layer perceptron artificial neural network (ANN), linear regression (LR), and random ...

To improve the selectivity between copper and lead, a sequential copper-lead-zinc rougher circuit was tested. Each of the rougher circuits had a dedicated regrind and cleaner circuit. The advantages of the sequential circuits are that the levels of selectivity can be increased, particularly for copper and lead.
