Ironworks
· Charging. After the ground ores have been processed in forms of sinter and pellets (see article iron ore mining and dressing), they are stored in bunkers in the iron works and mixed with lump ore as this mixture is then fed to the blast furnace together with coke as fuel, additives are added (also called fluxes).These mixture is referred to as charge.

be estimated from assays of material recovered from blast holes. But the lump and fines components will have different compositions, the lump usually being higher in iron and lower in other minerals. To estimate this lump to fines split, we need a "lump algorithm", a vector predicting the lump percentage yield, and the lump to fines difference in each mineral. Ores of different geological ...
Iron Ore Pelletizing Process: An Overview
In the blast furnace, iron is reduced and melted and the most common product is liquid iron called hot metal. In direct reduction, iron remains in solid state and the product is the socalled direct reduced iron (DRI). Generically, the iron ore products for ironmaking can be classified as shown in Table 1 . Pellets are balls formed by rolling moist concentrates and fines iron ores of different ...

Reduction Characteristics of High Phosphorus Iron Ore in ...
The present manuscript is aimed to investigate reduction properties of iron ores rich in phosphorous in order to study the suitability of using these ores in iron blast furnace. Representative technological samples of iron ore are collected from Eastern South Aswan iron ore mine in Egypt. The principal gangue contents are SiO2 %, and P2O5 %. Iron and phosphorus exist in the form of ...
Iron Ore
Blast furnace slag. By melting iron ore and reducing into molten pig iron in blast furnaces, slag forms. By replacing 40–70% of ordinary Portland cement with ground granulated blast furnace slag (GGBFS), the rate of bleeding increases. The advantage of using GGBFS as given by ACI is using an adequate amount of coarse aggregates without compromising the concrete workability and therefore, the ...
