Gold extraction - Wikipedia

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 Gold extraction refers to the processes required to extract gold from its ores.

Rock Crushing methods and How to recover gold from Ores

If you really are going to be working with ores from a hard rock mine, perhaps the best method for the small minor is the use of the a small shaking table. A good table is fairly bulletproof in one set up operates well on its own, and does an efficient job of capturing small gold particles.If you really are going to be working with ores from a hard rock mine, perhaps the best method for the small minor is the use of the a small shaking table.
