well as ore processing. Keywords Iron ore · Characterization · SEM–EDS · XRD · XRF · FTIR Introduction The most common element that makes up rock formations is iron, which accounts for about 5 percent of the earth's crust. India alone has a signicant reserve of iron ore in the world [1]. The two most common iron minerals, hema-
Electron transfer in natural iron minerals is a crucial process for their function in aquatic environments. This process can occur through various cellular metabolic pathways, where Fe(II) in natural iron minerals can serve as an electron donor for iron-oxidizing microorganisms under both aerobic and anaerobic conditions [9].This microbially-driven iron redox cycling …
