Heterogeneity Assessment for Grade Engineering in Complex Ore Bodies

Dr Craig Lindley
Session 6

Traditional methods of resource modelling and mine planning rely upon geostatistical methods applied to exploration drill core data to derive a three dimensional model of the distribution of metal grades….

Applying Enhanced Grade Engineering to Complex Ore Bodies

Robert Morrison
Session 6

The potential for taking advantage of “natural grade deportment” by size following blasting and crushing has been demonstrated for a range of ore types. Simple and low cost screening of…

New technologies that will potentially enable processing of complex orebodies

Dr Kym Runge
Session 9

There has been minimal innovation in the methods used to process an ore over the last 50 years.  Productivity increases have resulted in increased equipment size without implementation of parallel…

Dr Maedeh Tayebi-Khorami
Session 9

Two ore samples with different arsenic levels were selected from a complex ore body, named HAS (High Arsenic Sample) and LAS (Low Arsenic Sample). A Particle Kinetic Model was used…
