In order to describe temporal evolution of BET surface area of a mineral substance during an intensive milling process, a mathematical model in the form of S=a+b e−mt+c e–nt has been developed based on wellestablished phenomena in mechanical activation processes. Validity of the proposed model was verified by the results of experiments performed on a natural chalcopyrite mineral as well as those reported in the literature on a variety of sulfide minerals. It was shown that the model could fit different types of surface area variation with a very good accuracy.
