Dephosphorization of unroasted oolitic ores through ...
The present study of phosphorus removal from an unroasted iron ore via alkaline leaching method examined the possibility of dephosphorization from goethite ore at low temperature. The iron ore concentrate used in this study is an oolitic type of iron ore consisting primarily of goethite, in which phosphorus does not form a discrete mineral ...
Dephosphorization of High-Phosphorus Iron Ore Using ...
Mar 31, 2015 · High-phosphorus iron ore is traditionally dephosphorized by stone process with inorganic acids. However, this process is not recommended nowadays because of its high cost and consequent...

A hydrometallurgical process for the dephosphorization of ...
A process is proposed for the dephosphorization of iron ore. The process consists of an integrated treatment for the removal of the phosphorus from the ore by leaching and further processing of the leach solution. Phosphoric acid is extracted by isoamyl alcohol (iAmOH) and stripped by nitric acid solution.

Journal of Asian Scientific Research 2(12):840-855 852. shows that the percentage degree of dephosphorization for 10microns was 97.83% and that of 80microns was 93.04% for 16M concentration at leaching time of 30 minutes.
Removal of phosphorus from iron ores by stone leaching ...
Alkali-leaching and acid-leaching were proposed for the dephosphorization of Changde iron ore, which contains an average of 1.12% for phosphorus content. Sodium hydroxide, sulfuriced, hydrochloric and nitric acids were used for the preparation of leach solutions.

Processes for phosphorus removal from iron ore - a review
Zhang and Muhammad (1989) used nitric acid to remove phosphorus from the iron ore of the Kiruna region, Sweden. A concentrate of sinter, moist, and without treatment was used. stone analysis showed the composition of 0.98% phosphorus (as P 2O 5 22.25%) and 60.85% iron.
Dephosphorization of Steels – IspatGuru
Aug 15, 2016 · The initial comprehensive studies on dephosphorization were conducted during the 1940s. These studies observed that FeO and CaO are necessary slag constituents for the dephosphorization of steel. These studies also showed that the dephosphorization reaction is exothermic and that the slag capacity for dephosphorization decreases with temperature.
Comparative Assessment of Phosphorus Removal from Nigeria ...
The iron ore was found [1] to contain an average of 1.12% phosphorus and after the dephosphorization process, 91.61% phosphorus removal was attained with 1% sulfuric acid after leaching for 20 min at room temperature, during which iron loss was found to be negligible; less than 0.25%. The pH value

An integrated process for the treatment of apatite ...
A process has been proposed for the treatment of apatite concentrate obtained from the dephosphorization of iron ore. In this process, the apatite is acidulated by HNO 3 to produce high‐purity H 3 PO 4.The crude acid obtained is shown to be at least equivalent to, if not better than, the typical wet‐process acid.
