Effect of pH on Copper Flotation Recovery VS Mass Pull

Here, rougher flotation is most Selective at a pH of as pH levels in the 9 to 10 range yielded 1% to 2% better recoveries. Mineralogy data also supports this and shows between 3% and 10% of the copper is present as lowgrade middlings in pyrite, and further supports the benefit of floating middlings pyrite to maximize copper rougher recovery.
