  • 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 ...
  • Deoxidation and strengthening of steels using Fe-Ti-C master alloy 
    Malla, K.C.; Chakrabarti, A.K.; Galgali, R.K. (Ironmaking & Steelmaking, 25(2), 1998: 168-172)
    A Fe-Ti-C master alloy, prepared by carbothermic reduction of ilmenite ore in a transferred are plasma reactor, was tried out for deoxidation and dispersion strengthening of steels. Although it was not effective as a ...
  • Application of column flotation in the zinc cleaning circuit at Dariba concentrator Rajashtan, India. 
    Rao, G.V.; Das, B.; Chattopadhyay, P.; Sastri, S.R.S. (Transactions Of The Indian Institute Of Metals, 51(4), 1998: 187-192)
    Cleaning of the zinc rougher concentrate with flotation column indicated the possibility of producing a concentrate containing 53% Zn with 85% recovery while restricting the silica content to below 2% in single stage as ...
  • Alternative additives for zinc electrowinning 
    Tripathy, B.C.; Bhattacharya, I.N.; Krishna, P.G.; Das, S.C. (Transactions Of The Indian Institute Of Metals, 51(5), 1998: 303-310)
    About 80% of the total energy requirement in zinc production is consumed in the cell house. Increase in energy costs emphasises on searching for methods to reduce power consumption. Organic compounds other than glues or ...
  • Column flotation to recover molybdenite from Rakha Copper Concentrate - Part I: Conventional rougher flotation of molybdenite with sodium hydrogen sulphide 
    Rao, G.V.; Das, B.; Prasad, A.R.; Sahu, R.K.; Ansari, M.I. (Transactions Of The Indian Institute Of Metals, 51(6), 1998: 473-478)
    Rakha Copper Concentrator near Ghatsila, Bihar, India, produces 40 TPD beneficiated copper concentrate containing 24-25% Cu and 0.25% Mo. The in-house R&D of Indian Copper Complex at Ghatsila developed a flowsheet to recover ...
