The quality of the ore is heterogeneous, in some places consisting of disseminated magnetite and in others forming massive ore containing more than 50% magnetite. The mineralogy of the rocks of the Panzhihua intrusion and the magmatic ores have been described by Lu et al. ( 1988 ) and Zhou et al. ( 2005 ).

Abstract. The world's steel industry contributes 7–9% of global greenhouse gas emissions. This is principally from blast furnaces, basic oxygen steelmaking, sintering and pelletising. The push to reduce carbon emissions will see a change, where green high-grade magnetite with ≥68% Fe grade becomes the preferred feedstock for the steel ...

Magnetite is an important, strongly magnetic iron ore, along with hematite. Nanoinclusions of magnetite crystals cause the iridescence of Rainbow obsidian (Nadin, 2007). Extremely thin layers of 200-nm octahedral crystals of magnetite give some basalt surfaces an iridescent sheen (Nadin, 2007). May precipitate from supersaturated volcanic gas ...

However, since low-grade fine-grained magnetite ores generally require milling the run-of-mine (ROM) ore to particles finer than 45 m, it renders the conventional dry magnetic separators ine ective [7]. Additionally, spreading such fine-milled feed particles in a monolayer over a magnetic separator has a major dust pollution issue.

Over the last decade, there has been structural shift in the global iron ore markets favouring higher-grade, lower-impurity iron ore products. Generally, the lower the Fe grade of the iron-based feedstock, the higher the level of impurities such as phosphorus, silica, sulphur and alumina. More energy (i.e. coke) is required for blast furnaces ...
