Crushing Ore for Gold Veins - Hardrock Lode
Miners have been extracting free gold from hard rock sources for thousands of years. It simply requires that the ore be crushed and broken apart enough that the gold can be separated from the host material. Arrastras and stamp mills were commonly used at mines all throughout the world for this purpose.

Crushing is normally carried out on "run-of-mine" ore, while grinding (normally carried out after crushing) may be conducted on dry or slurried material. In comminution, the size reduction of particles is done by three types of forces: compression, impact and attrition. Compression and impact forces are extensively used in crushing operations while attrition is the dominant force in grinding
