Direct Reduced Iron and its Production Processes IspatGuru

Mar 16, 2013 Direct reduced iron DRI is the product which is produced by the direct reduction of iron ore or other iron bearing materials in the solid state by using non-coking coal or natural gas. Processes which produce DRI by reduction of iron ore below the melting point of the iron are normally known as the direct reduction DR processes.

Sulfurmediated electron shuttling during bacterial iron

May 30, 2014 Abstract. Microbial reduction of ferric iron FeIII is an important biogeochemical process in anoxic aquifers. Depending on groundwater pH, dissimilatory metal-reducing bacteria can also respire alternative electron acceptors to survive, including elemental sulfur S 0.To understand the interplay of FeS cycling under alkaline conditions, we combined thermodynamic geochemical
