In this paper, a sample from Tange-zagh iron mine was characterized by gravity and magnetic separation methods. The mineralogical studies showed that hematite and goethite are the main iron-bearing minerals with insignificant amounts of FeO. The results indicated that spiral separation yields higher separation efficiency than others. …
By improving the material fed to downstream plant processes, our magnetic separators reduce the mechanical requirements of grinding, ultimately lowering the overall cost. ... Our ferromagnetic wet drum separators can be used in iron ore separation plants in both rougher or cleaner beneficiation applications.
The experimental process was presented in Fig. 1 and comprised three stages, including magnetization roasting of iron tailings, alkaline leaching of roasted products, and magnetic separation of leaching residue. The roasted ore was leached with NaOH solution to remove Si-Al gangue minerals, following a procedure that entailed …
