  • Leaching of low grade Joda manganese ore with sulphur dioxide in aqueous medium 
    Naik, P.K.; Nathsarma, K.C.; Das, S.C.; Misra, V.N. (Transactions Of The Institution Of Mining And Metallurgy Section C-Mineral Processing And Extractive Metallurgy, 112(2), 2003: C131-C134)
    The feasibility of recovering manganese by leaching low grade ore with aqueous sulphur dioxide has been investigated. Successful extraction ivas achieved at atmospheric pressure and room temperature. The concentration of ...
  • Leaching of manganese nodule in hydrochloric acid in presence of sphalerite 
    Madhuchhanda, M.; Devi, N.B.; Rath, P.C.; Rao, K.S.; Paramguru, R.K. (Canadian Metallurgical Quarterly, 42(1), 2003: 49-59)
    This paper reports the results of hydrochloric acid leaching of manganese nodule and sphalerite in combination. Combined leaching was observed to be more effective than the individual leaching of either sphalerite or nodule. ...
  • Isopropylation of benzene over sulfated ZrO2-TiO2 mixed-oxide catalyst 
    Das, D.; Mishra, H.K.; Dalai, A.K.; Parida, K.M. (Applied Catalysis A-General, 243(2), 2003: 271-284)
    Zirconia-titania mixed oxide containing 60 mol% of zirconium was synthesized by co-precipitation method with and without sodium dodecyl sulfate (SDS) as surfactant. The 110 degreesC dried mixed oxides were loaded with 10 ...
  • Physico-chemical characterisation and photocatalytic activity of nanosized SO42-/TiO2 towards degradation of 4-nitrophenol 
    Samantaray, S.K.; Mohapatra, P.; Parida, K. (Journal Of Molecular Catalysis A-Chemical, 198(1-2), 2003: 277-287)
    Unmodified and sulphate-modified TiO2 samples of different crystal forms and crystal sizes were prepared at different pH, varying the source and concentration of sulphate ion and by activating at different temperatures. ...
  • Electroremediation of Cr(VI) contaminated soils: kinetics and energy efficiency 
    Sanjay, K.; Arora, A.; Shekhar, R.; Das, R.P. (Colloids And Surfaces A-Physicochemical And Engineering Aspects, 222(1-3), 2003: 253-259)
    Experiments have been conducted on Cr(VI) contaminated kaolin to determine the kinetics of electroremediation (ERM) and the associated rate controlling mechanism. ERM experiments of potassium dichromate contaminated kaolin ...
  • Mn-olivine from Gangpur Group of rocks, Orissa 
    Mohapatrai, B.K.; Nayak, Bibhuranjan (Journal Of The Geological Society Of India, 61(5), 2003: 581-587)
    Mn-olivine (tephroite) bearing assemblage is often recorded in manganese silicate-carbonate-oxide rocks metamorphosed to green schist facies condition in Precambrian Gangpur Group, Orissa. Divalent Mn and Fe dominate this ...
  • Influence of surfactants on flocculation and dewatering of kaolin suspensions by cationic polyacrylamide (PAM-C) flocculant 
    Besra, L.; Sengupta, D.K.; Roy, S.K.; Ay, P. (Separation And Purification Technology, 30(3), 2003: 251-264)
    This paper reports the result of studies on flocculation and dewatering of kaolin suspensions by cationic polyacrylamide (PAM-C) flocculants in presence of surfactants. The surfactants used were namely anionic sodium dodecyl ...
  • Morphology and analysis of gold grains associated with auriferous quartz veins, Gopur, Keonjhar district, Orissa 
    Das, S.K.; Nayak, B.K.; Chattopadhyay, P.; Muralidhar, J.; Nayak, B.B.; Singh, A.K.; Sahoo, R.K. (Journal Of The Geological Society Of India, 62(3), 2003: 335-342)
    At Gopur, Orissa, auriferous quartz veins with stringers and rich disseminations of sulphides occur in the laterites derived by tropical weathering of metabasaltic rocks. Minute to coarse irregular gold grains were hand ...
  • Band structure studies in solids using X-ray spectroscopy 
    Acharya, B.S. (Indian Journal Of Physics And Proceedings Of The Indian Association For The Cultivation Of Science-Part A, 77A(2), 2003: 103-107)
    The advent of X-ray photoelectron spectrometer and high energy synchroton sources have renewed interest in X-ray spectroscopical investigation of matter, be it solid, liquid or gases. Out of all spectroscopies available ...
  • Kinetics and mechanism of the reactions of chromium(III) and L-ornithine in aqueous solution 
    Mohanty, S.; Anand, S.; Brahma, G.S.; Mohanty, P. (Journal Of The Indian Chemical Society, 80(9), 2003: 810-814)
    The anation reaction of L-ornithine (H3L2+) with chromium(III) has been studied over the range 3.0 less than or equal to pH less than or equal to 3.5, 40degrees less than or equal to t less than or equal to 55degrees and ...
