A New Method for Handling Stubborn Gravity Middlings
July 2016 by Gavin & Randy ClarksonThe solution focused on the relative difference in malleability between gold and waste, rather than the difference in density exploited by gravity circuits.
There were nice sections of vein material at the end of several drifts, like they just stopped work one day and walked away.
I love to dry wash old nugget patches found by detector operators, and I have found my fair share of gold dry washing those areas. I have also found a few nuggets using a detector on the bedrock exposed by dry washing the patches.
It is not necessary to have a PhD in geology, but you need to know the basics, so that’s what I am going to try to dig into here—the understandable basics of these gigantic gold deposits.
Now it was time for the nerve-wracking part of the job: actually removing anything from the hanging wall we deemed to be in need of removal because it was either loose, could be loose, looked loose, or we felt it was just downright dangerous
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.
The Wyoming Geological Survey released an online interactive map...
“The evidence is clear—mineral deposits alone are not enough to attract precious commodity investment dollars...”
