Sand Washing Methods Of Fine Grained Iron Ores

Rock Crushing methods and How to recover gold from Ores

The classic old mortar and pestle was the method used by early day miners to crush their ore specimens for testing. You can still buy these things today at most prospecting stores - they are made of cast iron and last a long time and work fairly well. It just takes a lot of elbow grease and work to break up the rock.
