Most placer miners use classifiers to separate rocks and other overburden so they don't have to pan so much (or process so much). I have made my own screens and like 3/8" and 1/4" mesh. You can make them rectangular and shake side to side, you could make them circular and also shake these by rotation, and if you were a really big time gold prospector, you might have a motorized classifier. Many folks have come up with good ideas for these creations. I think this is a really well-made step by step account of making a classifier.
