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.

Iron ore–coal composite pellets/briquettes as new feed

2017-3-3  About 70% of the total production of the country’s iron ore is fines. Around 4 Mt of fine slimes (containing 55 to 60% iron) are generated every year by ore washing plants in India. 4 Mill scales are also the industrial by-product, which are produced due to hot working processes (such as hot rolling, forging and heat treatment of steel etc).
