| 1 | Effect of desliming on the magnetic separation of low-grade ferruginous manganese ore显示文摘In the present investigation, magnetic separation studies using an induced roll magnetic separator were conducted to beneficiate low-grade ferruginous manganese ore. The feed ore was assayed to contain 22.4% Mn and 35.9% SiO 2, with a manganese-to-iron mass ratio(Mn:Fe ratio) of 1.6. This ore was characterized in detail using different techniques, including quantitative evaluation of minerals by scanning electron microscopy, which revealed that the ore is extremely siliceous in nature and that the associated gangue minerals are more or less evenly distributed in almost all of the size fractions in major proportion. Magnetic separation studies were conducted on both the as-received ore fines and the classified fines to enrich their manganese content and Mn:Fe ratio. The results indicated that the efficiency of separation for deslimed fines was better than that for the treated unclassified bulk sample. On the basis of these results, we proposed a process flow sheet for the beneficiation of low-grade manganese ore fines using a Floatex density separator as a pre-concentrator followed by two-stage magnetic separation. The overall recovery of manganese in the final product from the proposed flow sheet is 44.7% with an assay value of 45.8% and the Mn:Fe ratio of 3.1. | Sunil Kumar Tripathy P.K.Banerjee Nikkam Suresh | 2015 | International Journal of Minerals,Metallurgy and Materials2015，22，7： | 6 |

| 3 | Effect of Indian Medium Coking Coal on Coke Quality in Non-recovery Stamp Charged Coke Oven显示文摘The maximum possibility of utilizing the Indian coking coals and inferior grade coking coal for producing metallurgical coke through non-recovery stamp charging technology was investigated.Indian indigenous coals contained low percent of vitrinite(<50%)and higher content of ash(>15%)compared to imported coking coal.Therefore,the selection of appropriate proportion of different types of coals was a major challenge for coke makers.Coal blend selection criterion based on a single coefficient,named as composite coking potential(CCP),was developed.The use of increased proportion of semi-soft coal(crucible swelling number of 2.5)and high ash(≥15%)indigenous coal in the range of 20%-35%and 20%-65%respectively in the blends resulted in good quality of coke.Plant data of a non-recovery coke oven were used for developing and validating the model.The results showed that the coke strength after reaction(CSR)varied in the range of 63.7%-67.7%and the M40value was between 81.8and 89.3in both the cases. | H.P.Tiwari P.K.Banerjee V.K.Saxena S.K.Haldar | 2014 | Journal of Iron and Steel Research(International)2014，21，7： | 2 |
| 4 | Artificial neural network approach to assess selective flocculation on hematite and kaolinite显示文摘Because of the current depletion of high grade reserves,beneficiation of low grade ore,tailings produced and tailings stored in tailing ponds is needed to fulfill the market demand.Selective flocculation is one alternative process that could be used for the beneficiation of ultra-fine material.This process has not been extensively used commercially because of its complex dependency on process parameters.In this paper,a selective flocculation process,using synthetic mixtures of hematite and kaolinite in different ratios,was attempted,and the adsorption mechanism was investigated by Fourier transform infrared(FTIR) spectroscopy.A three-layer artificial neural network(ANN)model(4-4-3) was used to predict the separation performance of the process in terms of grade,Fe recovery,and separation efficiency.The model values were in good agreement with experimental values. | Lopamudra Panda P.K.Banerjee Surendra Kumar Biswal R.Venugopal N.R.Mandre | 2014 | International Journal of Minerals,Metallurgy and Materials2014，21，7： | 1 |
| 5 | Magnetic separation studies on ferruginous chromite fine to enhance Cr:Fe ratio显示文摘The Cr:Fe ratio(chromium-to-iron mass ratio) of chromite affects the production of chrome-based ferroalloys. Although the literature contains numerous reports related to the magnetic separation of different minerals, limited work concerning the application of magnetic separation to fine chromite from the Sukinda region of India to enhance its Cr:Fe ratio has been reported. In the present investigation, magnetic separation and mineralogical characterization studies of chromite fines were conducted to enhance the Cr:Fe ratio. Characterization studies included particle size and chemical analyses, X-ray diffraction analysis, automated mineral analysis, sink-and-float studies, and magnetic susceptibility measurements, whereas magnetic separation was investigated using a rare earth drum magnetic separator, a rare earth roll magnetic separator, an induced roll magnetic separator, and a wet high-intensity magnetic separator. The fine chromite was observed to be upgraded to a Cr:Fe ratio of 2.2 with a yield of 55.7% through the use of an induced roll magnetic separator and a feed material with a Cr:Fe ratio of 1.6. | Sunil Kumar Tripathy P.K.Banerjee Nikkam Suresh | 2015 | International Journal of Minerals,Metallurgy and Materials2015，22，3： | 1 |
