- Dry Magnetic Separation Of Iron Ore Used In Kaolin In Hungary
This study aimed at the investigation of the effect of colloidal magnetic particles on the magnetic separation of iron ore tailings (IOT). For this, the synthesis and characterization of bare iron, iron-dextran, and iron-oleate magnetic particles is reported. FTIR spectra confirmed that the synthesized particles were composed by magnetite.

Introduction. In arid and severely cold regions such as west China, a plenty of iron ores are difficult to be economically utilized due to water scarcity [1,2], so that the utilization for such iron ores has an urgent demand for high-efficient dry magnetic separation (DMS) technology [[3], [4], [5], [6]].

Introduction. Ferruginous manganese ore deposits, typically with 15–35 wt% Mn, or with low Mn:Fe ratios (e.g. Mn/Fe of ∼0.5–2), are problematic for manganese alloy makers and thus manganese ore miners (Kivinen et al. Citation 2010).Olsen et al. (Citation 2007) state that the production of standard ferromanganese alloy with 78% Mn requires …
