WhatsApp: +86 18037808511Reducing gases (carbon monoxide and hydrogen) are used to remove the oxygen from the iron ore, resulting in a highly metallised iron product in pellet or lump form (depending on the type of iron ore feedstock, pellets or lumpy ore). The resulting DRI product is very porous in nature and as a result is highly reactive with a tendency to reoxidise.

United States Steel said Monday it will invest 60 million into its Gary Works steel mill in Gary, Ind., to produce pig iron. The pig iron, which will be fed into Big River Steel electric arc furnaces, will be made from iron ...
WhatsApp: +86 18037808511Iron ore is a crucial raw material for the global steel industry, and its supply chain is a complex network that involves multiple stakeholders and activities. The iron ore supply chain begins with the mining of iron ore, which is then transported to processing plants for beneficiation and further refinement. The refined iron ore is then transported to steel mills for use in the production of ...
