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;

So as you are crushing, stop and screen your material, removing any free gold which has already separated from the rock during your crushing that won''t go through your screen with your fingers. The coarser rock that won''t go through your screen can then be returned to the crusher for further work to break it down, and the fines won''t get in the way.

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.

For most small-scale gold prospectors, crushing ore to determine the amount of free gold is the best method to determine gold content within an ore sample. Free gold can then be collected using traditional gravity based methods, which do not require the same level of permitting as the chemical methods used by commercial gold mines.

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 is stockpiled (1) at the processing plant, and the process begins by feeding the ore into a hopper with a loader. The ore is conveyed, and lime is added (2) to raise the pH of the ore. Following crushing through a jaw crusher (3), the ore is fed into the semi autogenous grinding (SAG) mill (4) along with water and steel balls.
