Anyone can quickly learn to use the Cleangold sluice to recover free, fine and micron-sized gold. Non-motorized and non-mechanical, Cleangold quickly recovers fine gold to 5 microns.

Cleangold's specially prepared, patented plate creates a riffle system from magnetic sands, allowing excess materials to pass through the sluice while trapping gold. The only materials required for Cleangold to operate are ferromagnetic sands and water. If an ore source does not contain magnetite naturally, the Cleangold sluice can be pre-charged with recyclable magnetic sands or iron grains from manmade sources (e.g. iron lost at welding and grinding).

The dynamic nature of Cleangold riffles allow large amounts of material to be processed using laminar flow and small amounts of water. The high capture rate of the Cleangold method enables concentrates to be economically reduced by hand and gold can then be recovered without the use of mercury or cyanide. Cleangold uses little water and does not require clean water. Cleangold was specifically designed to work in low water flow conditions.

First pass recovery rates with Cleangold are at least 90% under static conditions with fine material. Because Cleangold processes ore quickly, tailings and concentrates can easily be rerun to further increase recovery. A small stream of water can process one tonne of heavy black sands in one hour. A 20 liter bucket of concentrates can be processed through the Cleangold Cleanup Trough in approximately five minutes, using about 20 liters of water.
