typical anionic collector for oxide mineral flotation is sodium oleate, the sodium salt of oleic acid, which has the structure shown in Figure 9. The anionic group responsible for attaching it to the mineral surface is the carboxyl group, which dissociates in water to develop a negative charge. The negatively-charged group is then attracted to positively-charged mineral surfaces

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

One of the major challenges faced by flotation of these ores is the ever varying grade and mineralogy. This therefore calls for a continual characterisation and optimisation of flotation parameters such that concentrator performance as a
