Crushing Ore for Gold Veins Hardrock Lode Mining Rock

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. On an even smaller scale, prospectors can crush up pieces of ore using a dolly pot, which is just a steel

Gold extraction

Gold extraction refers to the processes required to extract gold from its ores. This may require a combination of comminution, mineral processing, hydrometallurgical, and pyrometallurgical processes to be performed on the ore. Gold mining from alluvium ores was once achieved by techniques associated with placer mining such as simple gold panning and sluicing, resulting in direct recovery of small gold
