Sampling, Hydro-Shocking & Cleaning Quartz-Gold Specimens
May 2017 by Reese Townes
Many specimens have a small amount of gold and are not pretty to look at. There is a nifty way to give them a makeover and make them much prettier than they were when you found them.
I understand that a person without geological knowledge could be daunted reading a geological publication. You can pick out the good stuff from a geological publication without a lot of geological knowledge.
Before going into an analysis of the ore composition, two other major factors will affect the result. These are the accuracy of the assay and the effectiveness of the mill for the gold recovery.
The solution focused on the relative difference in malleability between gold and waste, rather than the difference in density exploited by gravity circuits.
Once all the numbers from all the samples and water tests are compiled, a snapshot of the performance of each tank in the process circuit can be seen side-by-side.
Prospectors have many reasons why they might want to break rocks. These include dividing up a specimen too large to carry.
After he excavates the ore down to bedrock, he goes over the bedrock with a metal detector to ensure he didn't leave any gold behind before he backfills the area.
