When would I use a Lerches Grossmann (LG) or Floating Cone (FC) optimisation methods and when would I use GMC Mine Scheduler?
GMC Mine Scheduler would normally be used after the LG and FC optimizations have been undertaken. The GMC Mine Scheduler facilitates the building of a cost model (from first principles if necessary). Since it also handles grades on dumps and techniques for ore blending are straight forward, it can be used to assign costs to the blending stockpiles that may be lying around for a period of time. The user may be able to assign penalties to those categories that cannot be blended at certain times, and/or assign corresponding value enhancements to those categories that are more desirable at certain times. These adjustments to ore values can be incorporated in subsequent re-runs of the LG or FC optimizations in order to optimise blending strategies in an iterative manner.
