“…There is lack of facilities for recycling of mill scale at the smaller capacity plants; due to absence of a sinter making facility in such units does not offer any scope for in-house recycling of mill scale. 5 Research works [5][6][7][8][9][10] have been carried out on various processes for use of mill scale as a charge material for iron and steel making. Due to fine size of mill scale, it is being agglomerated with or without carbonaceous material either by briquetting or sinter making.…”

“…Many sources Fe 2 O 3 apart from nature that they can be used as raw material for producing of permanent magnets Ba -Ferrite, one of which is the mill scale. A mill scale is a very attractive industrial waste due to its richness in iron oxide (about = 80 % Fe) [11]. The total content of iron oxide in the mill scale is quite high, so the mill scale can be used as an alternative raw material to produce barium hexaferrite.…”

“…Mill scale can be recycled in a steel plant to produce iron ore pellets, iron ore sinter, briquettes after mixing with a binder which used in the reduction process in iron making furnace. Also mill scale can be used in different applications like batteries, catalysts and mixed fertilizers [3,4]. Studies related to the reduction of iron ore using coke breeze have been discussed.…”

Mill scale is a valuable waste material that contains high amount of iron, little impurities and also is chemically stable composition. It is produced from the hot rolling processing in steel industry. The second waste is El-Dekheila pellets fine waste that produced as the results of handling in the El-Dekheila plant, West of Alexandria on the Northern coast of Egypt. This paper studies the recycling of mill scale and El-Dekheila pellets fine waste in iron and steel industries by reduction using coke breeze in the form of pellets. Characterization of raw materials were performed which are XRF, XRD and screen analysis. Reduction of pellets consisting of El-Dekheila pellets fine waste and different percentage of mill scale was investigated with 4 stoichiometric coke breezes using thermo-balance. The reduction increases with increasing coke breeze. The kinetics of reduction of these pellets were studied using different percentage of mill scale (20,60 and 80%) and at different temperatures ranging from 900 to 1050oC. The results displayed that the reduction process was controlled by Avrami and Erofeev involving nucleation of reduced phases followed by grain growth. Also, that the maximum reduction 80% can be reached after 125 minutes using 20% mill scale. The activation energies of reduced 20, 60 and 80% mill scale were found to be 112 kJ.mol-1 , 81 kJ.mol-1 and 107.8 kJ.mol-1 respectively
