Steel can be recycled and most steel mills primarily use recycled scrap steel instead of caste or pig iron from blast furnaces. Copper is also recycled. Once again this is a more energy efficient process than the extraction from its ore as well the copper ore supply on earth is being depleted at a very fast rate.
Production of Iron from Mill Scale Industrial Waste via Hydrogen
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

Study the Recycling of Red Mud in Iron Ore Sintering Process
Accordingly, the suitability of recycling this RM in the sintering process of Egyptian iron ore was studied. The effect of adding different amounts of RM to the sinter charge mixture (0-10 wt.%) on the sintering process performance as well as the chemical, physical and mechanical properties of the produced sinter was investigated.

Sintering : In sintering fine mineral particles are agglomerated into a porous mass by incipient fusion caused by the heat produced by combustion within the mass itself. In this case the iron ore fines and other iron bearing recycling materials are mixed with fluxing material, moisture and solid fuel normally coke breeze and fed to the permeable grate of sintering machine.
D.R.I. Fines Direct-reduced iron (DRI), also called sponge iron is produced from the direct reduction of iron ore (in the form of lumps, pellets or fines) to iron by a reducing gas produced from natural gas or coal. Few ores are suitable for direct reduction.
$69.75 per ton. Based on reported prices for iron ore fines (62% iron content) imported into China (cost and freight into Tianjin Port), the highest monthly average price during the first 8 months of 2020 was $121.07 per ton in August compared with the high of $120
2021/7/6A need for alternative iron ore units facilitated by metallics also is necessitated by the degradation of existing prime scrap, and scrap grades in general, as steel is continuously recycled. Pig iron imports also are projected to increase with the rise in sheet steel capacity in the U.S. as the tide turns to a more optimistic buying outlook.
Iron ores generally have higher grades than sulfide or gold ores, often going over 50 per cent or more. Less tailings are therefore generally produced in iron ore projects. In gold and silver mines, ore grades are generally in the range of grams per tonne.
