mercury demand for use in smallscale gold mining if the present, lavish Hg practices continue. At the same time, goldbearing placer or alluvial deposits are being exhausted in other areas, forcing many miners to give up mining and others to turn to hard rock mining, where the technique of amalgamation with Hg, generally, is not feasible [6].

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
