A typical anionic collector for oxide mineral flotation is sodium oleate, the sodium salt of oleic acid. 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.
