It's common wisdom that after leaving sulphide ore on the surface for a few years in a stockpile that flotation response may be affected.
Is anyone aware of a project where it was tested or predicted?
In a feasibility study, without mining the ore, having it sit there for 5 years, then testing it in the lab, how else might one represent how its performance might change?
Should we take a lead from the ARD/humidity cell guys and try to accelerate things?
Any published or private works on this would be fantastic.
This particular case is a copper sulphide in Peru, where there is different amounts of secondary copper minerals and varying pyrite by ore domain.
