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.
Most placer equipment is really made with gold in the 30 and larger mesh sizes in mind, though if carefully used can often get reasonable recovery down to the 50 mesh size.
I will make the assumption that when any of you take a detector in your hand and head out prospecting for gold you are probably anticipating finding some gold. That’s the general idea, right?
Improper sampling techniques lead to more avoidable heartache than almost anything else in micro mining.
Breaking cemented gravels
The solution focused on the relative difference in malleability between gold and waste, rather than the difference in density exploited by gravity circuits.
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.
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.
