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 colour of gold is due to the electronic structure of the gold atom which absorbs electromagnetic radiation with wavelengths less than 5600 angstroms
Gold ore whose types of deposits are diverse and complex is the mineral assemblage of gold. With features of chalcophile affinity and high melting point, the gold ore includes conglomerate type, porphyry type, quartz vein type and volcanic rock type, etc.
