Abstract
The effects of size distribution on the flotation behaviour of sphalerite have been investigated
in terms of kinetic parameters. In experimental studies, sub-samples of a Turkish sphalerite
ore were ground for different times using a laboratory ball mill. Timed batch tests were then
undertaken using a pilot flotation column and the resulting recovery/time data were used in
kinetic modelling. Results indicated that sphalerite floated rapidly at a medium particle size
distribution (d80 = 0.125 mm in this case). In addition, a statistical analysis of data
demonstrated that the flotation rate constant corresponded to a first-order model with
rectangular distribution of floatabilities given by the equation
