FLOWSHEET DEVELOPMENT FOR GOLD OREBODIES - sgs

is the presence of graphitic carbon in a gold ore This species, which occurs naturally in many orebodies, particularly in the SW United States and West Africa, is able to re-adsorb gold cyanide from the leach solution, lowering overall gold recovery Finally, refractoriness can be due to physical interference ie the inclusion of very fine particles of gold (usually < 1 micron in diameter

Gold processing | Britannica

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 (193 grams per cubic centimetre) has made it amenable to recovery by placer mining and gravity concentration techniques
