Separation by gravity If there is a certain difference in density between two minerals or rock fractions they can be separated by using this difference. • Separation in water (Gravity concentration).
Gold panning is the most common method used by small scale prospectors, but larger mining equipment like gold dredges, sluice boxes, drywashers, and many other types of equipment uses gravity separation to discharge lighter material while retaining gold.

A test to determine the amount of gravity recoverable gold (GRG) in ari ore is described. Typical GRG results are given; possible uses and typical diagnostics are prescntcd. Of the 38 samples tested, the lowest GRG content was found to be 25% (most below 25pm, or 600 mesh), and the highest 94% (most above 300 pm, or 50 mesh).
Gold, being the heaviest element we typically encounter in a stream, can be separated from lighter materials by various gravity separation methods. Gold panning is the most common method used by small scale prospectors, but larger mining equipment like gold dredges, sluice boxes, drywashers, and many other types of equipment uses gravity separation to discharge lighter material while retaining gold.
