Beneficiation Of A Low Grade Hematite Magnetite Ore In
In china, most reserves of rich iron ores have now been depleted and sustainable development of low-grade iron ores has become a critical discussion topic in the mining industry today. the aim of this study was to evaluate the applicability of beneficiating a low-grade, hematite-magnetite ore for subsequent utilization. In this study, process mineralogy and beneficiation low-grade hematite ores need to be upgraded to achieve the required iron content, which involves more complicated ore beneficiation processes. the level of comminution required for the low-grade hematite ore is similar to high-grade ores to deliver the same products, lumps and fines. get pricekoroznikova, begelhole, and mcknight, 2016. characterisation of low-grade hematite ore ultra-fine size fraction particles by heavy suspension, in proceedings the third ausimm international geometallurgy conference 2016, pp
