Gold readily dissolves in these solvents because of the formation of complex ions that are very stable. Gold (Au) melts at a temperature of 1,064° C (1,947° F). Its relatively high density (19.3 grams per cubic centimetre) has made it amenable to recovery by placer mining and gravity concentration techniques.
