Simple look at basic screens or classifiers. Uniform material makes for the best panning. Deciding how far down to screen depends on your patience and the size of the gold you are recovering. Probably small. I’ll try to put together a video that shows wet classifying, running coarse material down to fine.
In this video you’ll see regular screens and deep ones. Deep ones allow you to overfill a five gallon bucket just enough to work your material wet. They’re not meant to process more material, you really only want a screen a third full at the most when classifying.
