    Increase copper and gold recovery in a bulk flotation

    flotation process operates typically in two steps: 1. A gold-rich copper concentrate is produced where pyrite is depressed by the use of copper-selective collectors, pH control and the addition of sodium cyanide. 2. Following copper flotation, pyrite is recovered as a flotation concentrate which is then leached with

    2. Flotation of middling particles (i.e. higher than 200 m) improves with increased pH. This is true in the case when chalcocite is the major copper mineral. In the case of chalcopyrite ore, a lower pH is more desirable (i.e. 8.5–9.5) because at a higher pH, the flotation of chalcopyrite is decreased, especially for the coarser particles
