This is because the rocks have to be crushed to very fine gravels that can allow for gold molecules to be dissolved in mercury or any other chemical used to extract gold from the ore. What this means is that in large scale mining the mines may have more than one crusher (primary, secondary and tertiary crushers) in order to achieve the desired crushing levels.

Ore Processing Challenges in Gold Operation Grinding Circuits. By Scott Ferguson 06.16.2020. Continuous control of the final grinding product size is important to optimize gold liberation for gold milling operations. In addition, the live monitoring of the final product particle size leads to a maximum grinding circuit throughput.

The fine ore, will be sent to further milling, so that they are ideal for the leaching process. The ore, which is in slurry form, will be contacted with cyanide solution to dissolve its gold content. The solids that have been separated from the gold undergo a detoxification process to reduces the free-cyanide content level, to less than 50 ppm.

The process of gold ore processing and production mainly includes three processes: crushing, grinding and beneficiation. In the crushing process, the three-stage closed-circuit crushing is more modern and suitable for high-hardness gold ore crushing, which can complete the work of ore crushing and partial dissociation, thereby improving the subsequent grinding efficiency;

Arrastras were used by early miners to crush gold ore so that the valuable metal could be extracted. Most were powered by donkeys or oxen, although some were powered by waterwheels or even by the miners themselves. Crushing of ore was necessary to mine lode gold deposits.
