Advancements in Non-Toxic Gold and Silver Leaching
January 2019 by Chris Ralph
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.
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.
The Alaska state government has been trying to keep up with and maybe even stay on top of the situation by studying the problems associated with rapid growth and how to solve them.
I didn’t follow-up on this opportunity at that time, as I already had as much on my plate as I could handle, but the potential for this property has never left my mind.
For this article, I am focusing on industrial production plants that can handle 10 cubic yards per hour or more and would be fed by a loader or other heavy equipment...
These days they employ the use of metal detectors and carefully scan the shattered rocks, hoping to hear that sound we detectorists love to hear.
“The evidence is clear—mineral deposits alone are not enough to attract precious commodity investment dollars...”
Federal and state regulatory agencies often cite mercury and methyl mercury in our waterways as a major factor for further restrictions on placer mining, and on suction gold dredge mining, in particular. However, these regulatory agencies are minimizing selenium and its neutralizing effects.
