Processes for phosphorus removal from iron ore a review

The process of removing phosphorus from iron ore linked to the concept of selective agglomeration is well grounded in the work of Sirianni et al.. Sparks and Sirianni (1974) applied the technique to remove the iron ore’s phosphorus from Snake River, northern Canada. The content of phosphorus was in the range of 0.34% unacceptable for steel

Phosphorus Removal an overview ScienceDirect Topics

A longer leaching time was reported to result in lower phosphorus removal due to adsorption of phosphate ions onto the surfaces of the ore (Zhu et al., 2010). From another ore sample containing 37.5% Fe and 0.88% P, Jiang et al. (2008) obtained a gravity concentrate using spirals and a shaking table containing 58.7% Fe and 0.52% P, with an iron

Removal of phosphorus from iron ores by chemical leaching

Dec 01, 2006The results show that phosphorus occurring as apatite phase could be removed by alkali-leaching, but those occurring in the iron phase could not. Sulfuric acid is the most effective among the three kinds of acid. 91.61% phosphorus removal was attained with 1% sulfuric acid after leaching for 20 min at room temperature.
