Liberation modelling using a dispersion equation

This paper presents a new approach to model liberation for comminution. The liberation distribution is characterised by a dispersion rate function, which is related to the texture of the ore. Once this function is determined, the dispersion model predicts the liberation of the mill product when the feed or operating conditions changes. odel is validated using computer-simulated data and the dolomite-sphalerite data made available by Schneider (1995). The results show that the dispersion model is capable of describing and predicting the liberation of particles as size changes when breakage is non-preferential.
