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
The process used to extract gold involves strategically drilling and blasting rocks. Plans laid out by engineers and geologists prior to mining take a lot of preparation and often show the precise position of the gold within the rocks. As a result of this, miners are able to extract large quantities of gold-laden rock, referred to as the ore.
