phosphate floatation in iron ore

Anionic flotation of high-iron phosphate ores—Control of ...

2009-07-01  The main phosphate mineral recoverable by froth flotation is fluorapatite (Ca 5 (PO 4) 3 (F)). The main iron minerals are represented by hematite, goethite, magnetite, and siderite. KPO ores are also known to contain very small amounts of pyrite and pyrrhotite.

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. As ores become more complex, the need for tailor-made solutions ...

Froth Flotation of Iron Ores

2012-01-02  The mineralogy of phosphorus in iron ore depends on the type of iron minerals. In magnetite, phosphorous is often found in the form of discrete phosphorus containing minerals, which are referred to as apatite. Apatite is a group of phosphate minerals including hydroxylapatite, fluorapatite, chlorapatite, collophane and bromapatite.

Processes for phosphorus removal from iron ore - a review

Iron ore of high phosphorus content coexists with other minerals in the form of apatite or fluorapatite. Phosphorus is spread on the edge of mineral particles of iron oxide and embedded in quartz or carbonate minerals and a small amount is present in the iron mineral grid (Xia et al., 2011).
