摘要：

The effect of size distribution on the floatation 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 floatation column and the resulting recovery/time data were used in kinetic modelling. Results indicated that sphalerite floated rapidly at a medium particle size distribution (d(80) = 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: r = R-infinity{1 - 1/(k(2)t) over bar [1 - exp (- k(2)t]} (C) 2004 IoM Communications Ltd.
