Removal of Phosphorus From High Phosphorus Iron

2011-5-1  The content of phosphorus is generally a few times or even hundreds of times higher than that of common iron oresL†. In high phosphorus iron ores, phosphorus coexists with other minerals in the form of apatite or fluorapatite, disseminates in the edge of iron oxide mineral particles and embeds in quartz or carbonate minerals, and a small amount exists in the lattice of iron oresL2’.

Phosphorus Removal of High Phosphorus Iron Ore by

2010-9-1  A new method (gas-based separation plus melt separation) has been proposed to remove phosphorus of the high phosphorus iron ore which was 1.25% of phosphorus content and 50.0% of iron content. HSC chemistry package and the coexistence theory of slag structure were adopted for theoretical analysis.

Dephosphorization of High-Phosphorus Iron Ore

2015-3-31  The fact that phosphate removal from the high-phosphorus iron ore exhibited risings and falls rather than being continuous indicates that some of the phosphate microbially extracted from the high-phosphorus iron ore might be re-immobilized and released again . This suggests that a dynamic process is established between phosphate released and the parent ore surface or the microorganisms

Removal of Phosphorus from High Phosphorus Iron

In the process of resource utilization of high phosphorus iron ores, phosphorus should be removed first. Compared to other dephosphorization methods, selective leaching with acid has special advantages such as high dephosphorization ratio, low iron loss and so on. However, a large amount of acidic wastewater containing phosphorus was produced after acid leaching.
