Flotation of Iron Ore: A Brief Review MDPI

Fatty acids are widely used as a collector in the reverse anionic flotation of iron ores. The most popular anionic collectors used in iron ore flotation practice are oleic acid and its soaps 16,26. The oleate in aqueous solution forms different species and which species dominate is dependent on pH.

17 Flotation of Gold Ores

iron oxides, galena, arsenopyrite or copper oxides. The thickness of the layer may be of the order of 15 µm. Because of this, the flotation properties of native gold and its alloys vary widely. Gold covered with iron oxides or oxide copper is very difficult to float and requires special treatment to remove the contaminants.
