Collecting Agent–Mineral Interactions in the Reverse

The majority of studies on reverse flotation of iron ore focused on reagents and reagent scheme [9–13]. The reverse flotation route can be classified into reverse cationic flotation and reverse anionic flotation, based on the collector type. The reverse anionic flotation (flotation of gangue minerals using anionic collectors that mainly include fatty acids) was developed in the early 1960s

Froth Flotation of Iron Ores

02/01/2012· The flotation of iron ore started with the direct flotation of iron oxides using anionic collectors, but was latter largely replaced by reverse cationic flotation which has become the most widely used flotation route in the iron ore industry. The successful application of reverse anionic flotation in China’s iron ore industry in recent years offers a good opportunity to reduce costs while
