Jul 22, 2019· A mercury-gold amalgam then is formed because gold will dissolve in the mercury while other impurities will not.

The degree of purity of native gold, bullion (bars or ingots of unrefined gold), and refined gold is stated in terms of gold content. "Fineness" defines gold content in parts per thousand. For example, a gold nugget containing 885 parts of pure gold and 115 parts of other metals , such as silver and copper , would be considered 885-fine.
When gold dissolution is complete, the gold-bearing solution is separated from the solids. With ores of higher gold content (greater than 20 grams of gold per tonne of ore), cyanidation is accomplished by vat leaching, which involves holding a slurry of ore and solvent in large tanks equipped with agitators.
Gold Ore is a naturally occurring rare ore found in veins on planets and asteroids. It has a shiny yellowish appearance. Gold Ore can be processed in a Refinery to produce Gold Ingots at a 1% ratio.
