Stone quarry is an outdated term for mining construction rocks (limestone, marble, granite, sandstone, etc.). There are open types (called quarries, or open-pit mines) and closed types (mines and caves). For thousands of years, only hand tools have been used in quarries. In the 18th century, the use of drilling and blasting operations was mastered.

With the portable chain and hammer mill crushers now available, the cost for the small miner can be pretty reasonable. I own both a little jaw crusher and a small chain-based impact mill. My little jaw crusher can quickly break bigger chunks down to pieces of less than 1/8 inch, and the impact mill can grind the ore down to minus 20 mesh with
