My partner had the contacts and it wasn’t long before we had an agreement in place and the company had a geologist on site. I recall a time when he was getting the lay of the land, so to speak, and he broke off a rock sample and inspected it with his magnifier.
I thought it might be worthwhile to take a look at the basics of this important mineral separation technique and how a miner can use it to recover the values out of an ore.
A draft environmental assessment of a proposal to allow long-term camping by gold miners along 21 miles of the North Fork of the Fortymile Wild and Scenic River is available from the Bureau of Land Management.
In processing gold, silver and other valuable ores, the minerals containing the values, such as metallic gold, silver-bearing sulfides or other minerals, must be freed from the surrounding host rock before those valuable minerals can be captured.
Doug told me that there had been a 100-year flood that took place in October of 2013 and it washed out part of the mile-long landing strip. It also washed a large, wide gully down below and above the camp.
The non-toxic thiosulfate is actually the medical antidote given to people for cyanide poisoning. By accomplishing both neutralization and metals recovery, this process creates an economic and environmentally attractive process.
Ore testing and other advice for starting up a mining operation.
In part one of this two-part series on gold in Guyana, I describe artisanal mining efforts currently winning alluvial gold from small-scale placer operations located along the lower Puruni River and its tributaries.
