Characterization studies on Agbaja iron ore: a high

02/02/2019· Iron ores can be classified with respect to their phosphorus content as low-phosphorus ore (< 0.07% P), medium-phosphorus ore (0.07–0.10% P), or high-phosphorus ore (> 0.10% P) [ 5 ]. High-phosphorus iron ores abound worldwide and constitute the bulk of “low grade” iron ores.

Potassium and Phosphorous Bearing Ores of the Sishen

Since 1986, depletion of the richer iron ore deposits (>60% Fe; <0.24% K) worldwide necessitated the processing of lower*quality iron ore (<60% Fe; >0.24% K) (Personal communication*). Impurities, such as phosphorous (P) and potassium (K) contained within the lower*quality iron ore have a detrimental effect on the steel*making process, and therefore, steel*making plants charge penalties when

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). The most frequent and important constituent of the class of phosphates is apatite. Besides apatite
