Dear Colleagues,
We have just fire assayed our gold room concentrator tailings and it showed great losses, most likely due to a worn cone, low water back pressure and dirty water.
We have almost two years of tail dumps that now require reprocessing using a more efficient concentrator. However, I want to collect samples across these tails and then fire assay to confirm the average grade of gold in those mounds.
Most of the gold tails from that concentrator are minus 4mm.
How should I collect reliable and representative samples?
Close case auger drill?
How should I process these samples? Fire assay? Doesn't do much to test the samples using same concentrator that lost gold to the tailings in the first place.
I tried to upload pics but the system didn't do it.
Thanks all,
GHANA BOB
