Pulverize the rock by crushing it with a heavy mallet first, making certain to contain the bits. Put the material at the top of a sluice box and add water to push the rock down the slightly angled ridged slide. Gold typically collects within the ridges. Another option is to pan the pulverized rock to remove the rock from the pan and leave the gold.
