In What Rock Formations Can Gold Be Found? Sciencing

Apr 24, 2017 Intrusive rock is typically very hard and erodes slowly. This allows the surrounding rock to be worn away by wind and water, leaving only the harder rock in place. Heavy particles, such as gold, are likely to accumulate against the harder rock while the lighter materials are more easily moved away.

How to Test a Rock for Gold Sciencing

Mar 13, 2018 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.
