Testing a solution to the King liberation model

Abstract A solution to the King liberation model is proposed and tested against the results of King and liberation of sphalerite, galena and chalcopyrite from a complex sulphide ore. For the King data, good agreement is shown. For the complex sulphide data, the trend is correct, but calibration is required for a close fit. A potentially important use of the model solution is to predict liberation size of an ore at the exploration stage.
