Fine Gold Recovery. Separating Placer Gold Particles from

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.

Placer Mining Methods

Placer Mining Methods. The major flaw of the gravity separation method is that very fine gold, referred to as flour, flood, or colloidal gold, is lost in processing. Early miners recovered no more than 60% of assayed gold values, and as late as 1945 recovery of free gold averaged only 70-75% (Spiller, 1983).
