Hematite and magnetite are the most prominent iron ores. Most of the highgrade hematite iron ores (direct shipping ore (DSO)) are subjected to simple dry processes of beneficiation to meet size requirements. This involves multistage crushing and screening to obtain lump (− 31.5 + 6.3 mm) and fines (approximately − 6.3 mm) products. Low

2020226 Beneficiation of a lowgrade iron ore was investigated by combination of the lowintensity magnetic separation and reverse flotation methods. The main constituents of the representative sample were 36.86% Fe, 8.1% FeO, 14.2% CaO, 13.6% SiO2, and 0.12% S based on the Xray fluorescence, titration, and Leco analysis methods.

Advances In Low Grade Iron Ore Beneficiation, Low grade beneficiation techniques the occurrence of indian iron ore deposits are mainly of haematite magnetite goethite and siderite however world production for iron is mostly by extensive use of haematite and magnetite as principle oxide feed since in Beneficiation Techniques Of Magnetite
Exhaustion of highgrade magnetite resources and large demand for iron ore in the rapidly developing steel industry promotes the mining enterprises to exploit lowgrade magnetite. Lowgrade magnetite with a low content of valuable minerals is hard to be separated with the conventional separation process flow because of its high beneficiation costs.
