Froth flotation is a particle separation process used for collecting selectively the small fraction of valuable mineral from a mixed ore. Froth flotation is based on differences in particle hydrophobicity and is the largest tonnage separation process worldwide. In flotation, the particles, after being finely ground and suspended in water (the pulp), are treated with a surfactant to make the ...

This problem can be easily solved by taking into account the slope of the conductivity profile before the "discontinuity" in the calculation algorithm. As shown in Figure 2, the froth phase conductivity is quite constant so that the absolute value of the slope near the interface tends to infinity. For the operation with a threephase system, similar results were obtained. However, the ...
