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.

What Are the Benefits of Recycling Metal ThoughtCo

Recycling one ton of steel conserves 2,500 pounds of iron ore, 1,400 pounds of coal and 120 pounds of limestone. Water is also used in great quantities in the manufacturing of many metals. According to an industry source, through recycling steel the amount of energy conserved would be enough to power 18 million homes for an entire year.
