Abstract. This investigation deals with the effect of replacing some amount of Baharia high barite iron ore concentrate by mill scale waste which was characterized by high iron oxide content on the parameters of the sintering process., and investigation the effect of different amount of coke breeze added on sintering process parameters when using 5% mill scale waste with 95% iron ore concentrate.
in US) to obtain metallic iron powder by the reaction of iron oxide (magnetite, hematite ore or mill scale) and reducing gases (CO/H 2 ) under high temperatures (> 1000°C) . The reduction of iron oxides and various ores containing iron oxides have been studied in the past [3-8].
Mar 09, 2013 · Sintering is a thermal process (carried out at 1300 deg C to 1400 deg C) by which a mixture of iron ore, return fines, recycled products of the steel plant industry (such as mill scale, blast furnace dusts, etc.), slag forming elements, fluxes and coke fines are agglomerated in a sinter plant with the purpose of manufacturing a sintered product .
the ore is reduced to 3/4" or less, it moves out of the mill in a slurry solution. The mill discharge is screened at 1/4" on trommel screens attached to the mill. Ore smaller than 1/4" is pumped in slurry solution to the wet cobber magnetic separator, which begins the process of separating the iron from the non-iron material. The magnetic iron .

What exactly is Mill Scale and what is done about it. Home FAQs . "Process for de-oiling mill scale". Another patent suggests a mixing the mill scale with calcined lime followed by a burning process to form pellets. . The Chinese steel makers then mix the mill scale with the low quality iron ore and prepare it for feed to a sinter plant .
The taconite process of concentrating iron from low-grade iron-formation has been made possible by very large-scale operation and mechanization. Because of the low value per ton of iron ore, it is necessary to handle many millions of tons of rock as economically as possible.
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 .
