Extraction of Gold

Gold can be extracted by washing only when it is present as metal in the form of particles which are not too minute. The washing removes the specifically lighter parts of the material, the heavier gold particles sinking to the bottom. The process is applicable directly to gold- bearing sand, and to gold-bearing rocks after crushing.

Mining Technology in the Nineteenth Century | ONE

Placer miners used simple tools such as pans and bateas, rockers, sluices, Long Toms, and dry washers to separate free metals from gravels. They sometimes used mercury, which forms an amalgam with small particles of gold and silver. Miners used mechanical crushing and grinding machines to break up ores for further processing.

Gold drywashers have been used for decades, as they are a very efficient way to prospect for gold in dry conditions. Essentially, all gold drywashers accomplish their task in the same way. The gold is separated from the sand or sediment by bursts of air going through a cloth, using the density of gold and vibrations to separate the material.
