Unfortunately, this large reserve cannot be utilized for the production of pig iron due to its high sulphur and phosphorus contents. In addition, the ore cannot be beneficiated easily like Itakpe and Oshokoshoko iron ores because of its texture. This work studied the beneficiation, dephosphorization and desulphurization of Agbaja iron ore.
Dephosphorization Treatment of High Phosphorus Oolitic Iron Ore by Hydrometallurgical Process and Leaching Kinetics ... The dephosphorization of high phosphorus iron ore has been researched in many countries, such as physical separation, 6,7,8,9,10) bio-leaching, 11,12) flotation, 13,14) ...
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.
ABSTRACT: The purpose of this research effort is to determine the optimal factors for dephosphorization of a Nigerian Agbaja iron ore. The process The process parameters used in the study of optimization of dephosphorization includes pH, particle size, dwell time.
A study on the dephosphorization of Agbaja Iron Ore using hydrometallurgical process has been carried out. The central composite design of 23 response was formulated and used to develop a model equation. The optimized result of the equation using Matlab shows that 97.97% degree of dephosphorization ...

American Journal of Research Communication Ameh, et al., 2013: Vol 1(8) 44 [email protected] Successful attempt [1] has been made in the past to remove phosphorus from Changde iron ore.
The lining, which ha~ a thickness of 20 to 30 centimetres, is composed of blocks of" iron ore, the interstices being filled up with small ore. The surfime is glazed bv a preliminary heating while the furnace is turned with a speed of only 2, or 4 revolutions per minute.
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 ...
be Iron ore, Slag, Sludge and different phosphorus method, vacuum refining and Microwave radiation methods are some of the processes which are in use widely. Hitoshi Ono et al [16] studied the removal of phosphorus from LD slag by floating separation of Dicalcium Silicate during solidification. On slow cooling from high temperature the
We have been experimented the dephosphorization on three charges. With the first charge, on the load (approximately 3 tones), the following additions have been made: ˜ 40 kg CaF2, ˜ 60 kg iron ore (pellet), ˜ 80 kg lime. After melting, the composition of the metallic bath is presented in Table 3.
Amount of iron ore, ladle slag and lime powder were10 kg·t −1, 17.3 kg·t −1 and 17.0 kg·t −1, respectively. The amount of lime power was determined so as for charged agents of basicity to be 3.0.
Dephosphorization process of high phosphorus oolitic iron ore by acid leaching and leaching kinetics were investigated in the paper. The high phosphorus ore samples (51%T.Fe, 0.52%P) used in this work were analysed by SEM-EDS and XRD, which showed their oolitic structure and mineral phases.
