|In the last decade, Meloy developed the IAC - Interfacial Area Conservation - model of liberation. His work included three conservation laws and a mathematical tool called textural transform. This paper reviews the developments and applications of the IAC model. From simple spherical two-phase locked particles with planar interfaces, the model has been developed for curved interfaces and solids with complex textures. Moreover, complex shaped particles and ores having more than two phases have been considered. The model equations give the degree of liberation of the component phases for different ore textures – platy blocky and acicular - as well as for different sue distributions. Lockedness profiles are offered for defining the middlings composition, so that from the model it is possible to predict washability curves.|
