    How to Test a Rock for Gold | Sciencing

    Mar 13, 2018 California miners in the 1840s used sluice boxes to siphon gold from sand or crushed rock, and hobbyist gold miners use the same process today. 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.
