摘要
A high voltage pulse (HVP) breakage model was developed as a general modelling structure to represent the three HVP breakage indices: body breakage probability (the D-1-model), body breakage product fineness (the D-2-model), and body breakage product pre-weakening degree (the D-3-model). Relations between the HVP breakage indices and HVP pre-concentration characterisation curves were established. The preliminary result indicated that the HVP breakage model has the potential to predict the recovery of valuable metals from the calibrated model parameters. A t(n)-family of curves (t(n) is defined as cumulative percentage of product passing 1/n of the initial size) was used to describe the HVP breakage product size distribution. The t(n)-family of curves can be employed to estimate the product size distribution from the predicted t(10) values by the D-2-model.
