Presentation summary

Geometallurgical modelling and its application to mine planning

Conventional approach of mine planning is mostly based on the block model obtained from interpolation of the attribute of interest. However, this paradigm doesn’t allow considering the metallurgical variabilities and might leads to bias in scheduled mineral processing output. In this presentation, it is of interest to show that how the geometallurgical variables can be employed for further improvement of the mining activities including NPV and scheduling optimization. Nevertheless, modeling of those variables is challenging, insofar as the interrelationship correlation (bi-variability) is difficult to characterize. To circumvent this problem, enhanced geostatistical simulation methodologies can be employed that advocates modelling any non-linear characteristics between any variables. Among the geometallurgical variables, the geomechanical parameters describing the quality of rock might directly show such a complexity. In this context, reliable spatial models impact the optimization of crushing system and its related energy consumption, for which its spatial modeling contributes the mine planning optimization.
