The pulp (5 to 10% solids) was placed in a mixer with light oil, like kerosene, after which it was separated by differential sedimentation. After all these stages of processing and treatment, the initial ore which came with 54.6% iron, 0.39% phosphorus, resulted in a concentrate with 65.9% iron, less than 0.02% phosphorus and 5.3% silica.

Froth Flotation of Iron Ores - article.sapub.org

2012-1-2  In general, phosphorus is considered as a gangue mineral in iron ore because it makes steel brittle. High levels of phosphorus in iron ore attract a penalty and reduces the profit margin substantially[42]. The mineralogy of phosphorus in iron ore depends on the type of iron minerals.

Dephosphorization of High-Phosphorus Iron Ore

2015-3-31  High-Phosphorus Iron Ore. The ore sample used in this study was obtained from western Hubei province, China. The ore sample was ground to a particle size of 0.07–0.15 mm. X-ray diffraction (XRD) analysis showed that the sample was mainly composed of hematite (α-Fe 2 O 3) and a small quantity of quartz and apatite (Ca 2 PO 4 Cl and Ca 5 (PO 4) 3 F). The main chemical components of the ore ...
