  • Hydro and electrometallurgy in India - An overview 
    Das, R.P. (Transactions Of The Indian Institute Of Metals, 49(6), 1996: 745-752)
    The practice of hydro and electrometallurgy in India is relatively new. Aluminium and zinc industries are among the the major non-ferrous metals industries adopting this technique in India. India also has a sizable nuclear ...
  • Kinetics of iron precipitation at elevated temperatures from Fe(III)-H2SO4-(NH4)(2)SO4 system 
    Das, G.K.; Acharya, S.; Anand, S.; Das, R.P. (Transactions Of The Indian Institute Of Metals, 49(6), 1996: 803-815)
    In the present work a systematic study has been reported on the precipitation of iron from Fe(III)-H2SO4-(NH4)(2)SO4 system at elevated temperatures 150-250 degrees C. The effects of various parameters such as time, acid, ...
  • Titanium carbide reinforced steel composites 
    Galgali, R.K.; Ray, H.S.; Chakrabarti, A.K. (Transactions Of The Indian Institute Of Metals, 49(3), 1996: 119-126)
    In this study an attempt has been made to strengthen plain carbon steels by TiC reinforcement. A Fe-30% Ti-10% C master alloy was added in varying proportions to low carbon (0.05%-0.1% C) steel melts in a laboratory induction ...
  • Special issue on hydrometallurgy - Foreword 
    Das, R.P.; Ray, H.S. (Transactions Of The Indian Institute Of Metals, 49(6), 1996: U2-U2)
  • Processing of low grade graphite ores of Orissa, India 
    Acharya, B.C.; Rao, D.S.; Prakash, S.; Reddy, P.S.R.; Biswal, S.K. (Minerals Engineering, 9(11), 1996: 1165-1169)
    Low grade graphite samples containing 12.2-13.1% fixed carbon from Rajunagfena, Orissa, India have been investigated for characterisation and amenability to beneficiation. The graphite is of the well crystallised flaky ...
  • Mineralogical and chemical characteristics of the serpentinites from Boula-Nausahi igneous complex, Orissa 
    Mohanty, J.K.; Sahoo, R.K. (Journal Of The Geological Society Of India, 48(2), 1996: 161-170)
    The ultramafic rocks of Boula-Nausahi igneous complex have undergone extensive alteration resulting in the development of serpentinites. Petrographic and mineralogical observations have led to the recognition of two stages ...
  • Carrying capacity in flotation columns 
    Sastri, S.R.S. (Minerals Engineering, 9(4), 1996: 465-468)
    The equation proposed by Espinosa-Gomez et.al. for the carrying capacity in flotation columns is revised to give better fit to the data. Flotation columns are found to be normally operated around 60% of their maximum ...
  • Densities and viscosities of NiSO4-H2SO4-H2O system 
    Das, K.C.; Panda, D.; Singh, S.K. (Physics And Chemistry Of Liquids, 32(2), 1996: 123-126)
    Densities and kinematic viscosity data for the ternary system NiSO4-H2SO4-H2O were determined over a wide range of concentrations (0.93 - 1.36 mols. dm(-3)) and temperatures (20 degrees C to 60 degrees C). The results were ...
  • Extraction of iron(III) at macro-level concentrations using TBP, MIBK and their mixtures 
    Reddy, B.R.; Sarma, P.V.R.B. (Hydrometallurgy, 43(1-3), 1996: 299-306)
    Iron(III) extraction has been carried out at about 1 molar concentration from hydrochloric acid solutions using tri-n-butyl phosphate, methyl-iso-butyl ketone and their mixtures as solvents, Extraction increases with ...
  • Improved ionic mass transfer in an electrochemical cell in presence of turbulence promoters 
    Subbaiah, T.; Venkateswarlu, P.; Das, R.P.; Raju, G.J.V.J. (Hydrometallurgy, 42(1), 1996: 93-102)
    In industrial operations, reduction in equipment size can increase productivity, lower energy inputs and improve purity of the product. The presence of turbulence promoters in an electrochemical cell can increase the ...
