The treatment of copper–gold ores by ammonium

2002-10-1 · Copper–gold ores form a type of refractory gold ore. Large quantities of this ore type are available for processing. Cyanide treatment of ores with a high cyanide soluble copper to gold ratio is unfavourable due to high cyanide consumption resulting from the formation of copper–cyanide complexes.
