    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

    Mineral processing, art of treating crude ores and mineral products in order to separate the valuable minerals from the waste rock, or gangue. It is the first process that most ores undergo after mining in order to provide a more concentrated material for the procedures of extractive metallurgy. The primary operations are comminution and concentration, but there are other important operations in a modern mineral processing
