mining concentration gold

Gold readily dissolves in these solvents because of the formation of complex ions that are very stable. Gold Au melts at a temperature of 1,064176 C 1,947176 F. Its relatively high density 19.3 grams per cubic centimetre has made it amenable to recovery by placer mining and gravity concentration techniques.
