Selective Comminution - An Example of Quantitative microstructural analysis as support in ore benefication


Selective comminution exploits differences in the comminution behavior of the various minerals an ore comprises. The wider the difference in a material property to be exploited the better the components accumulate in different fractions of the comminution product. The waste portion can be rather easily excluded from further mineral processing by classification.

A suitable technology for selective comminution, considering the specific kind of loading generated by each type of crushers and mills, can be chosen on the basis of a quantitative microstructural analysis. Based on an ore analysis and its mathematical formulation, key parameters can be calculated in the form of mathematic values oriented to terms in geology.
