Anionic flotation of high-iron phosphate ores—Control of

Jul 01, 2009 The fatty acid flotation of a difficult-to-float igneous phosphate ore (26.2% P 2 O 5, 15.4% Fe 2 O 3) was investigated through batch flotation tests in the presence of soda ash.The poor flotation of this otherwise high quality ore was attributed to very high concentrations of calcium and sulfate ions (about 1000 and 2000 mg/L, respectively) found in

Flotation collectors optimized performance

Flotation of phosphate Phosphate ore is the most important source of phosphorus in fertilizers. To supply the phosphoric acid plant with phosphate, a high grade of phosphorus is essential, as well as reduced levels of impurities such as magnesium, iron and aluminum oxides. Flotation is one of the key beneficiation methods.
