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.
