Abstract

Abstract

Australia is rich in high-quality iron ore resources with high raw ore grade and low content of harmful elements, which can be directly smelted without beneficiation after mining. However, high-quality iron ore resources are not renewable. The development and utilization of lower grade iron ore resources is of great significance for the sustainable mining. An iron ore from Australia has a Fe grade of 57.93%. The mainly iron-containing minerals contain hematite, limonite, and a small amount of pyrolusite. The gangue minerals are mainly kaolinite and silica, followed by feldspar, biotate, calcite, white titanium, and rutile. The complex embedded relationship among the valuable mineral, the fine disseminated grain size of hematite as well as limonite inclusion were contained in kaolinite, silica which is not conducive to the magnetic separation of the iron ore. In this paper, a flow chart of magnetic separation-flotation was adopted to obtain iron ore concentrate with Fe grade of 68.57% as well as Fe recovery of 76.45%.
