Abstract [en]

Comminution tests are necessary in order to investigate mineral liberation achieved during particle size reduction and the mechanical energy needed for that. Depending on the type of the comminution process and equipment respectively, various test methods have been established in the past. Most of these tests require comparatively large sample amounts and are also costly in terms of time.Within the geometallurgical approach comprehensive information about the ore’s processing properties is required for building a spatial geometallurgical model of a deposit. Comminution behavior has to be quantified when modeling mill capacity and liberation. Providing comminution test methods that are efficient in terms of sample utilization and effort is therefore an essential task.This paper summarizes several different approaches to quantifying ore comminution behavior in the geometallurgical context. The methods examined at Luleå University of Technology comprise linking crushing and grinding characteristics to mineralogical parameters as well as correlating them with geotechnical tests, the down-scaling of standard grindability tests, and the further development of drop weight test methods.
