of hematite have been formed (Guba, 1982; Villalba et al., 2010). During these processes, magnetite and hema-tite are converted to each other by decreasing oxygen fugacity and increasing instability according to Equa-tion 1. This reaction takes place in the superficial parts of the magnetite veins. In this case, the formed hematite
The emergence of new magnetite mines could transform the landscape of Australian iron ore mining and ease the steel industry's ... but the typical hematite-goethite ores found in the Pilbara region are not suitable for beneficiation to higher grades. ... which typically need more investment compared with hematite direct shipping ore (DSO) mining.
Above we have mainly introduced the relevant beneficiation process of magnetite and hematite.But in the actual beneficiation plant, we also need to design the relevant beneficiation process according to the characteristics of the ore and the actual conditions of the beneficiation plant to choose the most suitable beneficiation process.
