Silica and Iron Recovery from a Residue of Iron Ore Flotation
A study of silica and iron recovery from the iron ore concentration tailing is presented. The residue is composed of 40.1% Fe, 33.4% SiO2, 8.31% Al2O3, 0.08% P, and 0.34% MnO. The developed process of silica and iron recovery consisted of size classification, magnetic separation, and removal of impurities by leaching. A concentration of SiO2 from 33.4% to 67.0%, with 60.0% of mass reduction, wa...
متن کاملRECOVERY 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...
متن کاملIncreasing efficiency of thickener operation in concentrate plant of iron ore mine using coagulation-flocculation
Thickener is a main and fundamental step in modern mining separation processes. In this research, the effectof flocculant consumption rate and feed solid concentration of settling rate of layers was studied with differentconcentrations in iron ore mine of Jalalabad, Zarand, Kerman, Iran. The experiments were performed in two1000 ml graduated cylinders (61 and 62 mm diagonal an...
متن کاملReverse flotation studies on an Indian low grade iron ore slimes
The present investigation deals with the recovery of iron values from the screw classifier overflow slimes from an iron ore washing plant by means of reverse cationic flotation as an alternate to direct anionic flotation. Selectivity index, an indicator of separation efficiency, was chosen as the response parameter for optimizing the quantity and evaluating a series of generically same but chem...
متن کاملSettling Rates for Flocculation of Iron and Manganese Ore-Containing Suspensions by Cationic Glycogen
Novel flocculants have been synthesized on the basis of glycogen. The efficiency of cationic glycogen can be explained in terms of Singh’s qualitative easy approachability model (EAM). The jar test was used previously to evaluate flocculation efficacy, but we have recently shown that a plot of interface height vs. settling times provides a better measure. In accord with the EAM, a one-to-one co...
