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 goldbearing rocks after crushing. The crushing is effected by stonecrushers, rollingmills

Rocks that contain visible gold veins usually have gold inside them. To make it accessible, extractors crush the rocks into small pebbles and then grind the pebbles into a powder. In days gone by, miners and prospectors did this with hammers and a mortar and pestle, but modern gold processors use large machines called crushers to make the pebbles. They feed the pebbles into other crushing machines to make a powder or slurry
