Abstract: The influence of different preoxidation temperatures and preoxidation degrees on the reduction and fluidization behaviors of magnetitebased iron ore was investigated in a hydrogeninduced fluidized bed. The raw magnetitebased iron ore was preoxidized at 800 and 1000°C for a certain time to reach a partly oxidation and deeply oxidation state.
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.
· It is a complied byproduct of converting iron ore or sinter to steel, which is produced ... In the same year in United States, it produces ∼ Mt of steel slag per year, with 85 ... When it comes to the iron oxide as alyst, the removal of contaminants by Fentonlike reaction alyzed by iron oxide has received a lot of ...
It is Coal Fuel based DRI. Coal based Spongeiron is a metallic product produced through direct reduction of iron ore in the solid state .As such it is also known as Direct Reduced Iron (DRI). Iron Ore Pellet is used for reduction. After reduction of iron ore pellet the product resembles sponge because of pores left behind after removal of oxygen.
Disclosed is a method for reclaiming iron and phosphorus from steelmaking slag, which comprises a first process, in which steelmaking slag that contains phosphorous, such as dephosphorization slag, is reduction treated using a reducing agent, such as carbon, Si, or Al, to reduce and recover iron oxides and phosphorus oxides in the slag as phosphoruscontaining .
· Phosphate removal is currently achieved largely by chemical precipitation, which is expensive and causes an increase of sludge volume by up to 40%. An alternative is the biological phosphate removal (BPR). Municipal wastewaters may contain from 5 to 20 mg/l of total phosphorous, of which 15 mg/l is organic and the rest in inorganic.
· Acidfree, waterbased industrial rust removers utilize a slightly different chemical process to react specifically with rust and remove it from the metal. While acids break down and dissolve rust, acidfree, waterbased rust removers draw the rust away or lift it from the metal. This process is generally accomplished through chelation.
solidstate carbonbased reduction technology and is applicable for processing iron ore as well as ironoxidecontaining materials (Mcclelland and Metius, 2003). Moreover, it has been applied for processing complex iron minerals such as vanadium titanomagnetite (Chen and Chu, 2014). The FASTMELT® process comprises two stages: direct reduction

· The first step in the metallurgy of iron is usually roasting the ore (heating the ore in air) to remove water, decomposing carbonates into oxides, and converting sulfides into oxides. The oxides are then reduced in a blast furnace that is 80–100 feet high and about 25 feet in diameter (Figure
· Of course, iron ore is not pure; it can contain impurities such as sulfur and phosphorous. Some of the impurities are separated out during smelting, forming a waste product called "slag". This is the purpose of adding lime: it acts as a "flux", that is, a material that helps separate out the slag.
Once it is absorbed into a molten manganese ore ferromanganese phase, it cannot be easily removed by smelting, and thus, ferromanganese must generally be low in phosphorus to begin with. As good quality ores of low phosphorus are depleted, the phosphorus content in manganese ores increases, and thus, the development of a new dephosphorization technology is needed.
· Abstract This paper reviews the applicable separation technologies relating to removal of heavy metals from solution and from soils in order to present the stateoftheart in the field. Each technology is briefly described and typical operating conditions and technology performance are presented.
