  • Electrochemical phenomena in MnO2-FeS2 leaching in dilute HCl. Part 1: Theoretical derivation of rate equations under various limiting conditions 
    Paramguru, R.K.; Kanungo, S.B. (Canadian Metallurgical Quarterly, 37(5), 1998: 389-393)
    The paper presents a theoretical analysis of MnO2-FeS2 dissolution in acidic media. It is assumed that MnO2 and FeS2 dissolve through the operations of MnO2/Fe2+ and FeS2/Fe3+ corrosion couples. Al the mixed potential E-m, ...
  • Molybdenite recovery by column flotation in the byproduct recovery plant of UCIL, Jaduguda 
    Rao, G.V.; Sastri, S.R.S. (Metals Materials And Processes, 10(2), 1998: 119-126)
    Molybdenite is recovered at Byproduct Recovery Plant (BRP) of Uranium Corporation of India Ltd., Jaduguda, from the bulk concentrate of copper, nickel and molybdenum by differential notation using sodium sulphide as the ...
  • Cation exchange and sorption properties of aluminum phosphate 
    Mishra, T.; Parida, K.M.; Rao, S.B. (Separation Science And Technology, 33(7), 1998: 1057-1073)
    The ion-exchange properties of amorphous aluminum phosphate have been studied in aqueous electrolyte solutions of KCl over a temperature range of 300-320 K. The data were explained by the law of mass action. Sorption of ...
  • Use of Thiobacillus ferrooxidans for iron oxidation and precipitation 
    Das, T.; Chaudhury, G.R.; Ayyappan, S. (Biometals, 11(2), 1998: 125-129)
    Fe(II) oxidation reaction was carried out using an acidophilic microorganism, Thiobacillus ferrooxidans. Four different parameters such as pH, Fe(II), Fe(III) and biomass concentration were studied. The oxidation reaction ...
  • Zinc electrowinning from acidic sulphate solutions - Part II: Effects of triethylbenzylammonium chloride 
    Tripathy, B.C.; Das, S.C.; Hefter, G.T.; Singh, P. (Journal Of Applied Electrochemistry, 28(9), 1998: 915-920)
    The effects of triethylbenzylammonium chloride (TEBACl) on the electrowinning of zinc from acidic sulfate solutions have been studied in the presence and absence of antimony(III). The factors considered included the current ...
  • Bio-oxidation of iron using Thiobacillus ferrooxidans 
    Das, T.; Panchanadikar, V.V.; Chaudhury, G.R. (World Journal Of Microbiology & Biotechnology, 14(2), 1998: 297-298)
    The effects of pH, ferrous and ferric ion concentrations on iron oxidation by Thiobacillus ferrooxidans were examined. The initial temperature and bacterial concentration were maintained at 37 degrees C and 2 +/- 1 X 10(4) ...
  • Leaching of Chromite overburden with various native bacterial strains 
    Acharya, C.; Kar, R.N.; Sukla, L.B. (World Journal Of Microbiology & Biotechnology, 14(5), 1998: 769-771)
    Four heterotrophic bacterial strains were isolated from soil and water samples from a chromite mine in Sukinda valley in Orissa. They were identified as Lactobacillus acidophilus, Staphylococcus lactis, Lactobacillus sp. ...
  • Synthesis and characterization of tetraphenylphosphonium halochromates 
    Patnaik, U.; Muralidhar, J. (Journal Of Thermal Analysis And Calorimetry, 53(3), 1998: 817-824)
    Ion-associated halochromates (halo = F, Cl, Br) from tetraphenylphosphonium cation (Ph4P+) are synthesized by stepwise solvent extraction technique and characterized based on XRD, spectral and thermal studies. The Ph4P+CrO3B- ...
  • Synergistic effects of LIX 64N and Fe3+ during copper electrowinning 
    Pradhan, N.; Krishna, P.G.; Das, S.C. (Transactions Of The Institute Of Metal Finishing, 76, 1998: 96-100)
    The synergistic effects of additive LIX 64N and Fe3+ during copper electrowinning from sulphate electrolyte were investigated The results show that the combination of LIX 64N and Fe3+ affects current efficiency, deposit ...
  • Wear characteristics of TiC reinforced cast iron composites Part 2 - Abrasive wear 
    Galgali, R.K.; Ray, H.S.; Chakrabarti, A.K. (Materials Science And Technology, 14(11), 1998: 1189-1193)
    The presence of carbide particles in metal matrix composites improves abrasive wear resistance properties. Abrasive wear characteristics of TiC reinforced cast iron composites have been investigated. The RC particle size ...
