Abstract
The phenomenon of liberation of binary phase mineral particles by frac ture at the interface is theoretically examined by consideration of th e fracture mechanics of brittle solids. Interfacial fracture leading t o liberation is naturally predicted by the effect of size on strength which is intrinsic to Weibull statistics. Application of the Brazil te st to sphalerite/dolomite specimens confirms the prediction and the pr esence of a critical size for liberation via interfacial fracture.
