Iron ore is vital to the steel industry, but as high-grade resources deplete, processing refractory iron ore becomes crucial. Techniques like gravity and magnetic separation face challenges in achieving optimal results due to the ore's complexity. Innovations in magnetization roasting offer efficient recovery methods, with suspension roasting proving superior in terms of efficiency and sustainability. The use of hydrogen in mineral transformations, as in HMPT technology, demonstrates significant benefits by enhancing iron extraction efficiency and reducing greenhouse gas emissions. Various studies have shown the effectiveness of HMPT in achieving high-grade iron concentrates while maintaining environmental sustainability.
