Jan 13, 2020 This study investigates upgrading of low-grade banded hematite quartzite iron ore (Fe ~31 ). Conventional beneficiation was found to be futile. The susceptibility of iron phases to microwave exposure and their selective absorption assists in the liberation of iron values. Microwave exposure of coarse particles at 540 W for 10 min yielded a concentrate with Fe 56.30 and recovery of 50.68.

Prior to enrichment, these sediments normally contained 20–30 Fe. Over time, the action of water leached the siliceous content and led to oxidation of the magnetite and enrichment of iron, forming hematite and goethite ore deposits. The grades of the ore and the impurity content varied with the extent of weathering and metamorphism.

Oct 24, 2021 In this study, direct reduction-magnetic separation process was applied to enrich phosphorus and iron to prepare Fe-P crude alloy from a high phosphorus oolitic hematite ore (HPOH). The results show that at lower temperatures and with absence of any of additives, Fe cannot be effectively recovered because of the oolitic structure is not destroyed. In contrast, under the conditions.
