Production of Iron from Mill Scale Industrial Waste via,

Mill scale is very attractive industrial waste due to its richness in iron (about = 72% Fe). In this paper, the characterizations of mill scale were studied by different methods of analyses. The produced mill scale briquettes were reduced with hydrogen at varying temperatures, and the reduction kinetics was determined. Two models were applied and the energy of activation was calculated.Disposal Methods on Solid Wastes from Mines in,01/01/2012· Open access under CC BY-NC-ND license. 716 Zengxiang Lu and Meifeng Cai / Procedia Environmental Sciences 16 ( 2012 ) 715 – 721 It is an effective way of solving the problem of waste discharge, land occupation and protecting environment if the mine solid wastes can be treated in new ways such as waste reuse, waste rock reduction and waste rock and tailings backfill.
