Ask The Experts: Equipment to break up heavy clay
January 2017 by Chris Ralph
Q: I am looking for a “trommel machine” that doesn’t separate anything but clay slurry from rock hard clay.
Explosives used correctly will save you both time and money being one of the best and most productive tools you can use.
I’ve had great success using it to gather gold from crevices. I’d like to share the design with all of you gold miners reading this article and hope that you get as much satisfaction building and using it as I did.
Ditches almost always started in the high country and contoured the mountainsides, making a long drop, usually many miles away, to the goldfields. There are ditches in Trinity County that originate at seven and eight thousand feet in the Trinity Alps that carried water almost thirty miles.
My intention was to end this discussion with waypoints and routes, then I found USGS maps of the Plainfield Quadrangle.
Perhaps the most notable thing about skim placers is that they form on the top surface of gravel bars, as opposed to coarser gold placers where the weight of the gold particles allows the gold to settle down on or near bedrock.
Bismuth oxide for assaying?
The solution focused on the relative difference in malleability between gold and waste, rather than the difference in density exploited by gravity circuits.
