RE:RE:RE:RE:RE:Rio Tinto labradorHere on SH we heard of an Operational issue / failure where Overheating occurred & Plasma Torch Tips melted as a result from Shutdown Failure -- could it be that was the issue & what U heard is from that situation?
IMO Sounds like a reasonable plaisible explanation of possibly old news -- i can't see it taking months to determine the Torches aren't Generating sufficient Heat where it's not Hot enough...
Regardless of whatever it may or may have been Testing Continues is Most Important!!!
