Rock Crushing methods and How to recover gold from Ores

The size of screen I use is 18 mesh and I think anything in the range of 16 to 20 mesh is a good size. I would not recommend going with anything larger than 10 mesh or smaller than 30. Finally, once the rock is fully crushed we get to the part about separating out the gold from the crushed rock. Often, this is accomplished simply by very careful panning. Panning is the most suitable method if ...
