Quantifying contributions to froth stability in porphyry copper plants

In the work by Runge et al. (2007), a correlation was found between copper grade of the concentrate produced by plant cells and froth velocity and collapse rate, which were calculated by automated image analysis of the top of the froth. A prediction of concentrate grade down the bank was formulated, based on froth velocity and collapse rate values.
