May 01, 1989  HydrometaUurgy, 21: 277-292. A process is proposed for the dephosphorization of iron ore. The process consists of an inte- grated treatment for the removal of the phosphorus from the ore by leaching and further process- ing of the leach solution. Phosphoric acid is extracted by isoamyl alcohol (iAmOH) and stripped by nitric acid solution.

Dephosphorization of High-Phosphorus Iron Ore Using ...

Mar 31, 2015  High-phosphorus iron ore is traditionally dephosphorized by chemical process with inorganic acids. However, this process is not recommended nowadays because of its high cost and consequent environmental pollution. With the current tendency for development of a low-cost and eco-friendly process, dephosphorization of high-phosphorus iron ore through microbial process with

Aug 06, 2013  In the dephosphorization slag process, the slag is magnetically separated into a phosphorous-rich (PR) phase and an iron-rich (IR) phase, and the phosphorous in the PR phase is subsequently converted to phosphoric acid. We included case studies that considered generation of potentially useful by-products, such as phosphogypsum and the IR phase.
