Gold deposits can be grouped into two primary classes: placer deposits, where the gold is exposed from weathering and erosion, and hard rock, where the gold is still trapped within the host rock. Gold recovery methods for these two types of deposits vary greatly from simple panning to a complex network of grinding, chemical leaching, gravity concentration and more.

placer gold rock gold concentrate ratio up to 99 on average. That means it''s not reliant on gravity settlement; the values are forced into the concentrate chambers by centrifugal force This yields a greater recovery of fine gold Since the Low-G is a batch-type concentrator, you can achieve very high concentration ratios with most types of alluvial and hard rock ores In fact, you achieve a

Or, rather than use a special device (wheel, bowl, etc), you can work your concentrates completely or nearly down to the gold with the use of a gold pan. In this case, I would suggest that you first classify the material through 8-mesh (8 openings per linear inch) and then through 20 mesh (20 openings per linear inch) screens to break it up into three sizes: 1) the material which stays on top

Hard rock mining, also known as lode mining, is obviously the best method for finding gold specimens since you are mining the true source of the gold by following veins of high grade ore into the mountain. Unfortunately, this type of mining is very expensive and not realistic for most small scale prospectors, but there are still methods that any prospector can be used to specifically target
