  • Reduction and foaming of FeO containing slag 
    Galgali, R.K.; Datta, P.; Ray, A.K.; Prasad, K.K.; Ray, H.S. (Ironmaking & Steelmaking, 28(4), 2001: 321-328)
    Smelting reduction processes being developed for producing liquid iron using coal and oxygen are attractive because they allow the use of ore fines directly and do not depend on coke. This paper presents a brief review of ...
  • Synthesis and characterisation of rare earth oxide based pigments 
    Nayak, R.; Rao, J.R.; Suryanarayana, A. (Journal Of Scientific & Industrial Research, 60(12), 2001: 941-944)
    An attempt has been made to prepare eco-friendly pigments, stable at high temperature, based on rare earth metal oxides as replacement to the presently available inorganic products based on lead, chromium, cadmium, and ...
  • Kinetics of iron oxide reduction in molten slag 
    Jouhari, A.K.; Galgali, R.K.; Chattopadhyay, P.; Gupta, R.C.; Ray, H.S. (Scandinavian Journal Of Metallurgy, 30(1), 2001: 14-20)
    Experiments on reduction of FeO in molten slag have been carried out using a graphite crucible in a 50 kW capacity plasma reactor. The crucible surface serves as reductant which implies that reduction of FeO takes place ...
  • Effect of pyridine and its derivatives on the electrodeposition of nickel from aqueous sulfate solutions - Part I: Current efficiency, surface morphology and crystal orientation 
    Mohanty, U.S.; Tripathy, B.C.; Singh, P.; Das, S.C. (Journal Of Applied Electrochemistry, 31(5), 2001: 579-583)
    The effects of pyridine and its derivatives on current efficiency, surface morphology and crystallographic orientations of electrodeposited nickel from acidic sulfate solutions were investigated. The results indicated that ...
  • Analysis of sintered products of iron ore fines by flame atomic absorption spectrometry using a matrix modifier 
    Chattopadhyay, P.; Datta, P.; Jouhari, A.K. (Fresenius Journal Of Analytical Chemistry, 369(5), 2001: 407-411)
    A very precise and accurate method for chemical analysis of sintered products (from iron ore fines in "pot grate furnace") is discussed. A matrix modifier/buffer (a mixture of KCl, tartaric acid, HCl and H2SO4) is used to ...
  • Diospyros melanoxylon leaves: A rich source of pentacyclic triterpenes 
    Mallavadhani, U.V.; Panda, A.K.; Rao, Y.R. (Pharmaceutical Biology, 39(1), 2001: 20-24)
    In a program designed to search for alternative uses of Diospyros melanoxylon leaves (bidi wrapper leaves), extensive chemical screening resulted in the isolation of nine pentacyclic triterpenes and beta -sitosterol. Out ...
  • Some aspects of characterisation, utilisation and environmental effects of fly ash 
    Mohapatra, R.; Rao, J.R. (Journal Of Chemical Technology And Biotechnology, 76(1), 2001: 9-26)
    A review on fly ash, an important but problematic waste material is presented. The article deals with several aspects of the characterisation, extraction of metal values leaching and associated environmental pollution ...
  • Preparation of zirconia-toughened mullite with dissociated zircon 
    Bhattacharjee, S.; Galgali, R.K.; Singh, S.K. (Minerals & Metallurgical Processing, 18(4), 2001: 200-202)
    A method for the preparation of zirconia-toughened mullite using dc plasma is presented. An indigenously developed 50-kW thermal plasma reactor is used for the preparation of zirconia-toughened mullite using a dissociated ...
  • Studies on reduction roasting of chromite overburden in a multiple hearth furnace for extraction of nickel and cobalt 
    Banerjee, G.N.; Tripathy, H.K.; Mohanty, J.N.; Datta, P.; Murthy, B.V.R.; Reddy, B.R.; Dey, D.K.; Sahu, S.C.; Tripathy, A.K.; Jouhari, A.K. (Transactions Of The Indian Institute Of Metals, 54(5), 2001: 193-198)
    A possibility of extracting nickel and cobalt from chromite over-burden (COB) of Sukinda, Orissa, containing 0.3 to 1.1% Ni and traces of cobalt (0,02 - 0.06%) using reduction roasting followed by ammoniacal leaching process ...
  • Extract of nickel from Indian lateritic ores by gas-phase sulphation with SO2-air mixtures 
    Kar, B.B.; Swamy, Y.V. (Transactions Of The Institution Of Mining And Metallurgy Section C-Mineral Processing And Extractive Metallurgy, 110, 2001: C73-C78)
    Lateritic ore with high iron (36-46%) and low nickel (0.8-1.1%) contents from the Sukinda region of Orissa, India, was sulphated with sulphur dioxide-air mixtures to give selective extraction of the nickel. Various roasting ...
