Formatted abstract A technique of analysing mineral breakage by using irradiated size fractions is developed. Particular emphasis is placed upon the special errors associated with such a technique.

The Broadbent-Callcott matrix analysis of breakage is found to be the most suitable to interpret these experimental results. Further investigation shows that their concepts are correct, but a simple model based upon the assumption of a constant selection function is not always adequate.

The practice of expressing the breakage function as a step matrix is shown to be valid, and its accuracy of predicting product size distributions under different conditions is exhibited. The procedure of postulating a standard breakage function is shown to be unnecessary, but convenient, since any breakage function suffices, provided that it is used in conjunction with its companion selection function.
