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 ...

the size of the leaching plant that would be required as well as reduces the amount of leaching reagents required. Many gold plants use conventional thickening with flocculant addition. High rate thickeners, as well as dewatering systems that use cyclones only or cyclones and highrate thickeners can also be used in principle.
