Classification will always give you the best results.
[SIZE=+1]
The very first thing I do is dry and classify.
Dry is always best when classification is going below 50 mesh.
When you are classifying, never go more than 2X the mesh size. I start with 8 mesh then 16, 20, 30, 50, 70, 100, 200, and 400 mesh.
Then I remove the magnetics from each size.
I get a little anal about the black sands, I store them all in their individual sizes. Someday I'll figure out why. I do have a video out there that shows my black sand removal technique.

My favorite pan style:
[/SIZE][SIZE=+1]The pan I like best is the black or green 10" with the bottom 1/4" dropped straight down. An angled bottom to side conversion can't stop the gold from climbing. The 1/4" 90º wall at the bottom will stop it dead in it's tracks. [/SIZE]

Then I start the panning process:[/SIZE][SIZE=+1]
Now all you have to do is start by normal panning to minimize your material, get as much light stuff out as you can over a catch pan. [/SIZE][SIZE=+1]I'll take care of the easy stuff first, 100 and above. Nothing special here,
The Golden Rule is, if everything in your pan is the same size, Gold RULES! [/SIZE]

This is the rub your belly pat your head part.
I back wash in the pan with water moving from front-to-back not round and round. I hold the pan, as a clock at 11:30 with my left hand on top, then I put my pocket knife or a rock in my right hand for tapping.
When back washing you are looking for the water to move up both sides and collide at 12:00, just like waves on a beach. This way, if there is any gold trying to get away from the edges, the wash current will send it back and center it.
When you are ready to clean the gold, settle it all at 12:00. With the left hand, grab the pan at 11:30 and grab the rock with the right. Start the wave motion, adjust the angle until the material just starts to move.
It's kind of a rhythm now. Tap the pan at 12:30 at a rate of about 3 taps per second. At the same time keep the wave action going at a pace of 1 second per cycle, front to back. Now if you think you can keep it straight, hesitate while the water is over the material at the far end of the pan, 12:00, for 2 taps then back wash. That little hesitation will really concentrate the gold in a smiley face. As the face shows up, you can stop tapping and just wash, then tap as needed to keep control of the gold. It's the sharp tap that persuades the little stuff to climb. Panning that little stuff is a real joy, but It does take some practice.
We made a 12 part video series on the Gold Cube site have a look.
