So as I had posted several months ago I had done some beach gold mining with my gold prospectors club here on the Peninsula last summer.
I had a container of concentrates that needed processing but lacked the time(due to work) and equipment to finish processing it.
This gold is very fine much of it is sub 400 mesh.
The best way to process this stuff is with a shaker table.
But those start at $1,200 for the cheapest ones and that wasn't in the budget for this project.
So for Christmas I ended up with a set of 4" classifiers and a Martin Miller table.
And I finally got a day on Friday to play with it a bit.
I will say the process is slow but it does save the fine gold.
I decided to start with my sub 100 mesh and only had time to run that size one time.
I need to rerun it as I did loose some over the the end but it was captured in the catch tub underneath. Part of that was my fault as I am still getting used to how this thing works.
For $250 it does work well as a cleanup device and the classifiers do make it that much easier to process.
it definitely takes some getting used to as you have to use the included brush to disturb the material so the black sands will work off the table.
I really did like the hole with the mounted gold vial underneath. Made it easy to just sweep the gold into the vial.
here's a few pics of the miller table working.
And some of the results!
I have no idea of the weight or value of this gold.
It was just a fun family activity on the beach with my kid and my friends from the club.
As you can see it did a good job of getting this gold really clean with virtually no black sands in it.
