Geopyörä Rock Breakage

Geopyörä is the state of the art in rock breakage characterisation testing and was developed to allow mining companies to test large quantities of samples at low cost for geometallurgical, comminution design and control applications.

The test uses small discrete samples from full or half one-metre section of drill core or less than a kilogram of crushed rocks, allowing its integration with geochemical analysis for better understanding of variability mapping, ideal for geometallurgical applications. The data measured by Geopyörä can be used to accurately estimate standard comminution parameters as well as rock mechanical properties including:

  • t10
  • Axb parameter
  • Energy and force distributions (i.e. probability of breakage)
  • Drop Weight Index (DWi)
  • Bond Work Index (BWi)
  • Point Load Test Strength Index (Is)
  • Uniaxial Compressive Strength (UCS)

Geopyörä allows more samples to be tested at a low-cost to better understand variability and minimise risks

Core Resources has an exclusive licence to use the Geopyörä device for characterising rock breakage parameters.
