Panning was the oldest and simplest way to separate gold from surrounding rock. It was the most basic method to obtain placer gold. The basic procedure was to place some gold-bearing materials, such as river gravel, into a shallow pan, add some water, and then carefully swirl the mixture around so the water and light material spilled over the ...
A small prospectors pick is also useful, and a magnet and a small amount of mercury should be carried to separate the gold from black sand after panning.Specialty stores and manufacturers can provide the more elaborate equipment, such as skindiving gear, ready-built sluices, and mechanical gold separation devices, if desired.

126.96.36.199 Gravity Separation Gravity separation relies on density differences to separate desired materials from host rock. Devices used include gold pans, sluices, shaking tables, and jigs. Gravity separation alone is used at most placer mines, and in combination with other methods and some lode miners. 188.8.131.52 Ore Preparation
184.108.40.206 Placer mining Placer mining is used when the metal of interest is associated with sediment in a stream bed or floodplain. Bulldozers, dredges, or hydraulic jets of water a process called hydraulic mining are used to extract the ore. Placer mining is usually aimed at removing gold from stream sediments and floodplains. Because placer

Gold placer existed in native gold, the particle sizes was coarse from 0.11.0 mm, those that were less than 0.074 mm has little gold, and no colloidal clay, and it was washing gold placer. But the water shortage was the big challenge for this project.
Feb 29, 2016 Riffles separate heavy and light particles. Gold recovery with sluices can vary depending on several factors. Fine gold losses can be minimized by cleaning up more frequently, reducing the speed of the slurry flow to around 0.50 to 0.80 ms., and decreasing the feed size by performing a previous screening.
