In copper ores, other valuable minerals such as gold occur in trace proportions (0.5–2 g/t) (Allan and Woodcock, 2001). Optimising their flotation recovery leads to significant increase in value to the operation. In the flotation of copper–gold ores, the flowsheet is designed to produce a bulk flotation concentrate of chalcopyrite and gold.
