Removal of phosphorus from iron ores by chemical 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.

Chemical dephosphorization methods for iron ore were reviewed and tested on the ore samples from the Pilbara region. Leaching without thermal treatment was found to be quite ineffective.

Removal of Phosphorus From High Phosphorus Iron Ores

The selective HCl leaching method was used to remove phosphorus from high phosphorus iron ores. The hydroxyapatite in high phosphorus iron ores was converted into soluble phosphate during the process of …

A hydrometallurgical process for the dephosphorization

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.

Thermodynamic analysis and experimental study of

process from dephosphorization (using De-P and De-C converters) in the duplex melting process is advantageous, as it allows for the use of phosphorus-rich iron ore and relatively lower amounts of slag, as well as direct alloying with manganese ore in the converter. Consequently, iron procurement costs and metal losses are reduced to a .

Optimization of Process Parameters for the

The result in table 1 shows that the iron content of Agbaja iron ore is high and if the iron ore is properly beneficiated and dephosphorized can be used in steel making (Chime et al, 2011). In table 2, the chemical analysis of the deslimed iron ore is shown. The effect of desliming is not significant though it
