Abstract
Among other things, a process for generating hydrogen by valorizing iron ore tailings (IOT) through the oxidation of remnant ferrous iron phases in the tailings is described. The IOT may be either wet (i.e., containing water) or dry (i.e., not containing water). The reaction may be performed using untreated IOT and may generate hydrogen gas capable of being used on site.
Claims20
A method of generating a hydrogen gas product from an iron ore tailing (IOT), the method comprising:
- feeding the IOT into a reactor;
- mixing the IOT in a reactor resulting in the hydrogen gas product and a slurry waste;
- and
- collecting the hydrogen gas product from the reactor.
