    Gold processing preparation of the ore for use in various products.. For thousands of years the word gold has connoted something of beauty or value. These images are derived from two properties of gold its colour and its chemical stability.The colour of gold is due to the electronic structure of the gold atom which absorbs electromagnetic radiation with wavelengths less than 5600 angstroms A stamp mill consists of a set of heavy steel (iron-shod wood in some cases) stamps loosely held vertically in a frame in which the stamps can slide up and down. They are lifted by cams on a horizontal rotating shaft.As the cam moves from under the stamp the stamp falls onto the ore below crushing the rock and the lifting process is repeated at the next pass of the cam.
