Gold processing | Britannica

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 stabilityThe colour of gold is due to the electronic structure of the gold atom, which absorbs electromagnetic radiation with wavelengths less than 5600 angstromsIt is a rare element and occurs along with deposits of platinum, nickel, copper, silver and gold and is therefore obtained as a byproduct of mining these metals ie PGM Palladium was discovered in 1803, in London, by English chemist William H WollastonPalladium element extraction method – Deep
