A methodology for estimating froth recovery in large scale plant flotation cells is proposed. The primary aim of the technique is to estimate the froth recovery in a way that is simple, inexpensive and non-intrusive. Plant engineers can use the estimate of froth recovery in day to day trouble-shooting and circuit optimisation.

This has allowed a flotation cell to be modelled using the chemical reactor analogy; whereby the removal of solids from the pulp phase is defined by a first order rate equation. This means a bank of cells can be approximated by perfectly mixed CSTR's in series (Gaudin, 1957, Niemi and Paakkinen, 1969, Atkins et al., 1986, Yuan et al., 1996).

1. Introduction. Fournier et al. (2015) reviewed the impact of air distribution down banks of cells reported at several plants. That there would be an impact is not unexpected, but Cooper et al. (2004) appear to be the first to engineer the distribution, referred to as 'air profiling'. They showed on a Zn cleaner that an increasing profile, that …
