Rock Crushing methods and How to recover gold from Ores

So as you are crushing, stop and screen your material, removing any free gold which has already separated from the rock during your crushing that won't go through your screen with your fingers. The coarser rock that won't go through your screen can then be returned to the crusher for further work to break it down, and the fines won't get in the way.
