Optimisation of operating variables of fine coal flotation ...

2003-1-1  The actual values of R ∞ (obtained at the “flotation time”) and k s obtained in the lab tests were used to draw the time recovery curves for combustibles and ash. Fig. 1 shows a typical time recovery curve for combustibles and Fig. 2 shows a plot of ln(1−(R/R ∞)) vs. time t.The figures clearly show that the flotation tests follow a first-order rate equation.

Abstract Optimisation of flotation parameters using rate models is not a new concept. The kinetic model based on time recovery data, which uses the extra dimension of rate, has been in vogue since time immemorial for scaling up of lab data. Often, interpretation on the performance of a flotation circuit, based only on R ∞ (the ultimate recovery) and k s (the first-order rate constant of the ...
