Consequences of fractal grade distribution for bulk sorting of a copper porphyry deposit

Coghill, Peter; Miljak, D; Williams, Elizabeth


We show the presence of fractal ordering of copper grade in bore core data at short range in the Cadia Ridgeway porphyry deposit and measure its persistence after mining by monitoring the output of the mine every 20 s for a month using a large scale, zero field magnetic resonance sensor. A simple model is used to investigate this connection and its consequences for sorting of the ore. Fractal distributions, and their associated power laws, have two features highly favourable for segregating...[Show more]
