Steelmaking processes
To remove the phosphorus the bath of metal must be oxidised to a greater extent than in the corresponding acid process, and the final quality of the steel depends very largely on the degree of this oxidation, before deoxidisersferromanganese, ferrosilicon, aluminiumremove the soluble iron oxide and form other insoluble oxides, which produce nonmetallic inclusions if they are not removed ...
Occurrence of aluminum and phosphorus in iron ores.
· The presence of phosphorus in high amounts in the iron ores can make the steel brittle, favoring the appearance of cracks. In the present study eight samples of iron ores coming from Vale's mines were used. Sequential extractions were made to remove specific forms of phosphorus. The residues of these extractions, as well as the original samples, were characterized by Xray diffraction ...
Recovering and recycling phosphorus from incinerated waste
then treated twice with sodium hydroxide — an intermediate step to remove unwanted iron and aluminium metal contaminants. The remaining solution containing the phosphorous was then treated a second time with sodium hydroxide to create a solid phosphorus residue. This method extracted 72% by weight of the phosphorus that was originally present in the fly ash. The final product contained 3% ...
Phosphorus removal from aqueous solutions containing low ...
for removing phosphorus (P) with low concentration from aqueous solutions. The crystallinity, porous texture, mag netic susceptibility and performance in P removal of pyrite calcinates depended on calcination temperatures. The sorbent obtained at calcination temperature of 500–600 C possessed the most efficient P removal. Solution pH in the range of – and anions of chloridion (Cl ...

· The phosphorus concentration in the reject water was reduced by 90% during bioreduction of iron ore. The phosphorus removal rate did not depend on specific surface area of iron ore particles when the particle size of iron ore was smaller than 7 mm. The organic carbon removal rate did not seem to be dependent on iron ore particle size. CONCLUSION: Removal of phosphate using iron ore can .
Extracting iron
in a huge container called a blast furnace. Iron ores such as haematite contain iron(III) oxide, Fe 2 O oxygen must be removed from the iron(III) oxide in order to leave the iron behind.
Phosphorous removal from wastewater
In this process the chemical added are only iron and aluminium, lime is added only for pH correction. Lower costs and more simplicity are contrasted by a phosphorous removal efficiency lower than with postprecipitation (below 85%). The phosphorous concentration in the final effluent is about 1 mg/l. Another disadvantage is that biological and chemical sludge are mixed, so they cannot be used ...
