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 side.
Density sorting to separate solids fractions using differences in their dry material specific gravities provides for highly efficient yield of valuable product. The PHOENIX HYDROSORT Hindered Settling Classifier utilizes a fluidized bed of slurry for density sorting of lightweight contaminants from sand, silica sand and heavier minerals.
