One more thingBecause FPX has no sulfide nickel in the mix, LIMS can be used right up front in the rougher stage. This is a huge advantage due to greatly reduced reagent consumption in flotation.
Assuming an optimistic 7% insitu magnetite, .15% awaruite, a bit of chromite and some gangue still stuck to these after milling to 150 micron, we are looking at regrinding and flotation of only about 10% of the amount of ore mined. Maybe 15KTPD out of 150 KTPD mined. Keeps the plant size small.
