Iron and steel slags are coproducts of iron and steel manufacturing In the production of iron, the blast furnace is charged with iron ore, fluxing agents, usually limestone and dolomite, and coke as fuel and the reducing agent The iron ore is a mixture of iron oxides, silica, and alumina From this and the added fluxing agents molten slag and The use of lowgrade, refractory and composite paragenetic mineral resources is necessary for overcoming the shortage of iron ore resources in China As a solution to the treatment of such iron ores, the direct reduction of carbonbearing pellets can ensure complete iron removal and the effective enrichment of other highvalue elements Reaction characteristics of carbonbearing pellets of Bayan
3 Feeding the crusher (Reclaim) The surge pile allows a constant supply of material to be fed into the mill, which ensures consistent results and stability in the ore recovery process 4 Grinding The primary grinding mill grinds the material before it With highquality iron ore grades with an iron content of 64 to 67 %, a blast furnace typically produces about 025 to 030 t of slag per t of pig iron In the case of inferior grade ores below 60 %, the amount of slag is typically 035 to 050 slag/t of pig iron [1]Slag recycling recovery
A steel plant needs a slag processing plant for several reasons: Environmental considerations: Steel production generates a lot of waste material, including slag Slag is a byproduct of the Slag is a byproduct in the ironmaking process of blast furnace In the process of iron making, iron oxide is reduced to metallic iron at high temperature, and impurities such as silica and alumina in iron ore react with lime to form molten substances with silicate and aluminosilicate as the main components, which are quenched and Rotary Slag Dryer for drying Blast Furnace Slag in Portlant

AbstractThe effect of interfacial tension on the kinetics of the dephosphorisation of iron has been investigated Xray monitoring of the shape of a molten iron droplet in liquid slag showed that there was a marked reduction in the interfacial tension γms during periods of rapid mass transfer and an increase in γms as the mass transfer process slowed down, The use of lowgrade, refractory and composite paragenetic mineral resources is necessary for overcoming the shortage of iron ore resources in China As a solution to the treatment of such iron ores, the direct reduction of carbonbearing pellets can ensure complete iron removal and the effective enrichment of other highvalue elements Reaction characteristics of carbonbearing pellets of Bayan
With highquality iron ore grades with an iron content of 64 to 67 %, a blast furnace typically produces about 025 to 030 t of slag per t of pig iron In the case of inferior grade ores below 60 %, the amount of slag is typically 035 to 050 slag/t of pig iron [1]Therefore, the use of natural ores or industrial residues, with good availability and low price, is economically attractive for the BCLG process Low cost materials tested for BCLG includes iron ore (hematite) [18], [19], manganese ore [18], steel converter waste (LD Slag) [20] and ilmenite [21] In general, these materials were able toAssessment of the chemical looping gasification of wheat
