GENERAL PROCESS
The ENERGIRON Direct Reduction Process is designed to convert iron ore (pellet/lump) into metallic iron by the use of reducing gases in a solid-gas moving bed shaft furnace. Oxygen is removed from the iron ore by chemical reactions based on hydrogen (H2) and carbon monoxide (CO), for the production of highly metallized DRI. ...

A novel advanced reduction process for the reduction of …
At present, several studies have been reported on the reduction of Cr(VI) using ARPs. A novel g-C 3 N 4-modified biosynthetic Fe(III)-hydroxysulfate, with the assistance of citric acid and visible light, producing ·O 2-and Fe(II), could efficiently reduce Cr(VI) [15]. In addition, the co-existence of citric acid and oxalic acid with sulfidated …
