Conversion of Sponge Iron From Low Grade Iron ore And Mill Scale Through Simulating Tunnel Kiln Condition

Effective Beneficiation of Low Grade Iron Ore Through Jigging Operation

The effectiveness of jigging operation for the beneficiation of low-grade iron ore deposits of Orissa, India has been investigated. Iron ore sample obtained from Barbil region of Orissa containing very high amount of silica and alumina was crushed using the laboratory jaw crusher and roll crusher to prepare different particle sizes. The sink and float tests were carried out to evaluate the poss...

Characterization of Sangan low-grade iron ore and its processing by dry low-intensity magnetic separation

In Sangan iron mine nearly two million tons of low-grade iron ore has been extracted and deposited in the mining site and currently no action is made on them. On the other hand, the mining site is located in the semi-arid region and wet processing has been restricted due to water shortage. In this research, the upgradation of Sangan low-grade iron ore from mine B has been performed by dry low-i...

Beneficiation of a low-grade iron ore by combination of wet low-intensity magnetic separation and reverse flotation methods

Beneficiation of a low-grade iron ore was investigated by combination of the low-intensity 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 X-ray fluorescence, titration, and Leco analysis methods. The mineralogical studies by the X-ray diffraction, scanning electron mi...

RECOVERY OF IRON FROM LOW-GRADE HEMATITE ORE USING COAL-BASED DIRECT REDUCTION FOLLOWED BY MAGNETIC SEPARATION

In the present work, iron recovery from a low-grade hematite ore (containing less than 40% iron), which is not applicable in common methods of ironmaking, was studied. Non-coking coal was used as reducing agent. Reduction experiments were performed under various coal to hematite ratios and temperatures. Reduction degree was calculated using the gravimetric method. Reduced samples were subjected...
