ratio of fe phos in sponge iron lumps

Iron ore is used mostly in pellet and/or lumpy form. Oxygen (O2) is removed from the iron ore by chemical reactions based on H2 and CO for the production of highly metalized DRI. In the direct reduction process, the solid metallic iron (Fe) is obtained directly from solid iron ore without subjecting the ore or the metal to fusion.

Sponge iron. Sponge iron, also known as direct reduced iron (DRI), is a high-purity, metallurgical-grade iron (Fe) product produced by the direct reduction of iron ore in the form of lumps, pellets, or fines into iron by a reducing gas or carbon monoxide produced from natural gas or coal. This process reduces the oxygen content in the iron …

found that autotrophic denitrication and Fe3+-based phos-phorus immobilization were enhanced in iron carbon (Fe–C) layer. Moreover, it was proven that the microbial abundance related to denitrication process increased notably due to the addition of iron scraps and activated carbon (Shen et al. 2019).

Sponge Iron. We are the leading manufacturer of Direct-reduced iron (DRI), also called sponge iron, which is produced from the direct reduction of iron ore (in the form of lumps, pellets, or fines) by a reducing gas produced from natural gas or coal. We are manufacturing high-grade sponge iron that is consistent in its quality.

The process includes warming the normally occurring iron oxide in the presence of carbon, which produces "sponge iron." In this process, the oxygen is taken out without melting the ore. Chemical Specifications of the direct reduction of are given below: – 3Fe 2 O 3 + CO →2Fe 3 O 4 + CO; Fe 3 O 4 + CO → 3 FeO + CO 2; FeO + CO → Fe +CO 2
