Production of magnetite nanoparticles from Ethiopian iron ore using ...

Sakthivel et al in their work prepared magnetite powder using iron ore tailing. A fraction of the extracted FeCl 3 solution was changed into FeCl 2 via metallic iron formation using NaBH 4 as a reducing reagent. The magnetite particles synthesized in different ways showed varying degrees of magnetization behavior, credited to the change in ...

Enhancement effect and mechanism of iron tailings powder on concrete ...

The development of iron and steel industry requires the exploitation of a large number of iron ore resources. While producing iron concentrate powder on demand, a large number of eliminated tailings will be produced [1, 2].According to statistics, tons of tailings will be produced for each ton of iron concentrate powder screened on average.
