Some researches [1 5] have evaluated ways of achieving successful dephosphorization of iron oxide ore and also predicting removed phosphorus concentrations using empirical models. A model was derived for predictive analysis of the concentration of phosphorus removed during leaching of iron oxide ore in.View More
An innovative process of coal based reduction followed by magnetic separation and dephosphorization was developed to simultaneously recover iron and phosphorus from one typical high phosphorus refractory iron ore. The experimental results showed that the iron minerals in iron ore were reduced to metallic iron during the coal based reduction and the phosphorus was enriched in the metallic iron.View More
Coal based reduction followed by magnetic separation is an effective way to recover iron from high phosphorus containing oolitic hematite ore. Given that high quantities of dephosphorization agent are needed to obtain low phosphorus reduced iron, a novel approach is proposed by the authors. Without prior phosphorus removal, the phosphorus was enriched in the reduced iron during a reduction.View More
The iron concentrate, assaying 94.12wt Fe and 0.07wt P at the iron recovery of 96.83 and the dephosphorization rate of 74.08 , is obtained under the optimum conditions. The final product (metal iron powder) after briquetting can be used as the burden for steelmaking by an electric arc furnace to replace scrap steel.View More
This paper proposes a novel process for the pre treatment of high phosphorus iron ore by pre reduction, air jet milling and screening methods. The dephosphorization behavior was evaluated as a function of such parameters as the milling gas kinetic energy, E k and specific energy consumption, E sp .View More
Deposits of low grade and high phosphorus iron ores are spreading globally, however, the usage of this kind of deposits in the manufacturing of steel bounded because of the high phosphorus content as well as depression of iron in which affect the quality of the produced steel. The Bajrawia iron ore deposit is one of the largest in Sudan but it only contains (35.5 Fe) and undesirable amount of.View More

Mill scale is one of waste materials which is produced as a result of hot rolling of steel in all steel companies. On the other hand, mill scale is considered a rich iron source with minimum impurities. This work aims at conversion of mill scale by adjusting smelting processes to produce different valuable products. The smelting processes were carried out using carbothermic reduction in a.View More
In the process of resource utilization of high phosphorus iron ores, phosphorus should be removed first. Compared to other dephosphorization methods, selective leaching with acid has special advantages such as high dephosphorization ratio, low iron loss and so on. However, a large amount of acidic wastewater containing phosphorus was produced after acid leaching.View More
Iron ore beneficiation is a multistage process that raw iron ore undergoes to purify it prior to the process of smelting, which involves melting the ore to remove the metal content. The process of iron ore beneficiation has two complementary goals classifier on dephosphorization of iron ore illia massive machines iron ore mineral processing.View More
Jun 02, 2017 Basic oxygen furnace slag (BOF slag) is an unavoidable by product of steelmaking process of basic oxygen furnace. The main chemical constituents of BOF slag are CaO, FeO, Al 2 O 3 , SiO 2 and MgO. Due to its high metallic value (FeO 16 20 ) and lime content (CaO 45 50 ), it is possible to use in iron making and steelmaking process to replace lime and recover iron and CaO.View More
