چکیده
Hematite fines were found to form aggregates with magnetite ~des in the same slurry, without the help of any flocculants. Because of this aggregation. fine iron ores containing hematite and -anetile can be successfully concentrated by multi-stage deslimings. ~ that the ore is finely ground and silicate gangues properly ~rsed. The effectiveness of this technique has been tested on a UMIIIIIercial scale(lOO ton/h). The increased magnetic attraction MtweeD magnetite and hematite due to the terrestrial magnetization of magnetite and its size effect are revealed as responsible for the Igregation. considering the fact that the hematite-magnetite system k already in relatively week dispersion because of their low zeta ~

Neyzar iron deposit is located about 50 km southwest Mashhad, northeast Iran. It was developed as layered and discontinuous lenses in a fault zone within quartz-arenite and sub-litharenite sandstones of Lalun Formation (Lower Cambrian). Mineralographical studies show that hematite is the principal iron ore mineral accompanied by goethite and lesser amounts of pyrite. Microscopic examinations c...
متن کاملDetermination of Relationship between Autoignition of Sponge Iron and Specification of the Iron Ores
Sponge iron (DRI) due to the high surface area, often shows a high tendency to re-oxidation and at some cases spontaneous combustion (autoignition). In this work, re-oxidation behavior and autoignition of sponge iron, produced from different types of iron ore has been investigated. Isothermal and non-isothermal re-oxidation experiments were carried out on each type of DRI and their autoignition...
متن کاملDetection of Zones Based on Ore and Gangue Using Fractal and Multivariate Analysis in Chah Gaz Iron Ore Deposit, Central Iran
Detection of mineralized zones based on ores and gangues is important for mine planning and excavation operation. The major goal of this research work was to determine the zones based on ores and gangues by a combination of fractal and factor analysis in the Chah Gaz iron ore (Central Iran). The Concentration-Volume (C-V) fractal method was carried out for Fe, P and S, which indicated that the ...
