phosphorus iron ore impurities . Iron ore Wikipedia The Lowergrade sources of iron ore generally require beneficiation, using techniques like crushing, milling, gravity or heavy media separation, screening, and silica froth flotation to improve the concentration of the ore and remove impurities.
Extraction of Iron. ... and it is added to the blast furnace to remove the impurities in the iron ore. Calcium carbonate is decomposed by heat in the furnace to give calcium oxide and carbon dioxide. This is called thermal decomposition (see examples of other carbonates). ... The main impurity is silica (sand or rock) which is silicon dioxide.
a b s t r a c t The bacterium Burkholderia caribensis FeGL03, isolated from a Brazilian highphosphorus iron ore, was used to mobilize the phosphate contained in the same ore.
Introduction to Iron Ore and Steel Smelting Processing. Here the ore is put into a blast furnace along with limestone and coke and subjected to hot air blasting and heat which converts the ore to molten iron. This is tapped from the bottom of the furnace into molds known as pigs and allowed to solidify into pig iron.
The ore carries from to 3 per cent. phosphorus, averaging 1 per cent.; the average iron content is 58 per cent. The texture of the ore materially aids in the saving of the apatite, as it consists of sharply defined crystals of the different minerals whose cohesion is low.

The contents of C and S in iron ore samples were determined using combustion and IR absorption. The Si and Al contents were determined using XRF after fusion in Na 2 B 4 O 7. The contents of the other elements in iron ore such as Ti, P, Pb, Mg, Mn, Zn, and Cu were determined using ICPOES.
1. Phosphorus: The quantity of phosphorus present in pig iron varies from to %. It combines with iron to form Fe3P which embrittles cast iron. Phosphorus is introduced into iron from phosphate in the ore. Phosphates get reduced in the reducing atmosphere in the blast furnace and phosphorus is formed.
