  • Simultaneous dissolution of sphalerite and pyrolusite under the cyclic action of a redox system in acidic media 
    Rao, K.S.; Paramguru, R.K. (Metals Materials And Processes, 8(2), 1996: 193-201)
    The paper presents studies on dissolution of both sphalerite and pyrolusite under the cyclic action of ferrous-ferric redox couple in acidic medium. Sphalerite is oxidised by ferric ion, whereas pyrolusite is reduced by ...
  • Feasibility of iron recovery from iron ore tailings for iron and steel making 
    Das, B.; Reddy, P.S.R.; Prakash, S.; Biswal, S.K.; Rao, R.B.; Sengupta, D.K. (Solid Liquid Separation In Mineral And Metallurgical Industries, 1996: 113-122)
    Beneficiation of iron ore tailings from washing plants in India is essential as a prelude for utilising in sinterfeed. Investigations carried out by hydrocyclone on Bolani iron ore slimes have shown that it is possible to ...
  • Enhancement of mechanical dewatering of fine clean coal by surface active additives 
    Singh, B.P.; Besra, L.; Reddy, P.S.R.; Sengupta, D.K. (Solid Liquid Separation In Mineral And Metallurgical Industries, 1996: 130-139)
    This paper describes couple of dewatering approaches which were found to be very effective in providing filter cakes containing less than 12 percent moisture. These approaches involved addition of flocculant followed by ...
  • Kinetics of aluminothermic reduction of MnO2 and Fe2O3: A thermoanalytical investigation 
    Sarangi, B.; Sarangi, A.; Ray, H.S. (ISIJ International, 36(9), 1996: 1135-1141)
    This paper presents the main kinetic parameters for aluminothermic reduction of MnO2 and Fe2O3. Aluminothermic reduction which in fact is a redox reaction requires an initial input of heat which is obtained through external ...
  • Performance of solid bowl centrifuge in de-watering coal water slurry 
    Das, S.; Mohanty, B.; Murty, J.S. (Solid Liquid Separation In Mineral And Metallurgical Industries, 1996: 205-211)
    The use of High G Solid Bowl Centrifuge for dewatering of coal water slurry is studied with reference to hydraulic transportation of coal. The variables studied are effect of fines and temperature on the cake moisture and ...
  • Evaluation of some organic additives for zinc electrowinning from sulphate solutions 
    Das, S.C. (Transactions Of The Indian Institute Of Metals, 49(6), 1996: 781-788)
    The effects of pyridine and some of its derivatives on deposit quality, morphology, crystallographic orientation, polarisation characteristics, current efficiency and power consumption for zinc electrowinning from sulphate ...
  • 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)
