Experience has shown that an appropriate model for liberation ofsolid phases must always integrate all available mineralogical data by comminution. The present work aims to describe a case study for calibration of a liberation model with data obtained from semi-quantitative mineralogical analysis (ore microscopy). For the specific case of random comminution, a limit probability argument is used to justify the introduction of Euler's Beta Law as a well-suited tool for describing the liberation state of a comminuted ore, because it is able to predict the grade distribution of a given iso-size fraction of such a particulate system. The liberation algorithm is linked with a phenomen...
