Sponge iron is a highly processed form of iron ore which contains metallic iron in the range of 83-88% obtained by direct reduction without melting it. Due to high porosity, the resulting iron is called sponge iron. It is used as a raw material for manufacturing steel …
Oct 30, 2019· Sponge iron (s-Fe0) is a porous metal with the potential to be an electron donor for denitrification. This study aims to evaluate the feasibility of using s-Fe0 as the substrate of wetland mesocosms. Here, wetland mesocosms with the addition of s-Fe0 particles (CW-Fe) and a blank control group (CW-CK) were established. The NO3−-N reduction property and water quality parameters (pH, …
