Dejavoo - I feel the ramp up for PGI has been poor to date, Xstrata had tested the process with a pilot plant which came up trumps, but to date PGI seems to not have been able to replicate the pilot pant results.
Having the incorrect sized nozzles installed in the ag tanks plus an isa mill that is too small plus incorrect impellers/gearboxes installed: to me seems to imply there are serious concerns about the systems in place for the implemantation of the albion process.
How can it be recommended for future projects given whats occurred at PGI ?
THe high grade of Los Lagunas tailings mean it will probably still be quite profitable even if tonnage processed and recoveries are below name plate long term, so I still hold.
