  • Thermal, analysis studies on multimetal sulphides: Characterisation, roasting and leaching 
    Rao, K.S.; Ray, H.S. (Transactions Of The Indian Institute Of Metals, 52(4), 1999: 171-196)
    Thermal analysis (TA) studies have been made to understand changes in mineralogy that occur when pure sulphide minerals, single concentrates and different Cu-Zn-Pb sulphide concentrates are heated in air. The observed ...
  • Thermal decomposition of molybdenite in a plasma reactor and preparation of ferro-molybdenum 
    Galgali, R.K.; Bhattacharjee, S.; Patnaik, N.; Gumaste, J.L. (Transactions Of The Indian Institute Of Metals, 52(5), 1999: 289-298)
    A brief review on thermal decomposition of molybdenite is presented. Studies on experimental investigations on thermal decomposition of molybdenite and preparation of ferro-molybdenum in a plasma reactor have been made. ...
  • Preparation of TiC reinforced steel composites and their characterisation 
    Galgali, R.K.; Ray, H.S.; Chakrabarti, A.K. (Materials Science And Technology, 15(4), 1999: 437-442)
    Carbine reinforced steel composites are useful in extensive wear resistance applications. Titanium carbide reinforced steel composites harle been prepared by dissolving a TiC rich Fe-TiC master alloy in a liquid steel. The ...
  • Surface hardening of high carbon steel by plasma focus nitriding 
    Borthakur, T.K.; Sahu, A.; Mohanty, S.R.; Nayak, B.B.; Acharya, B.S. (Surface Engineering, 15(1), 1999: 55-58)
    Energetic nitrogen ions from a plasma focus device were utilised for the first time to nitride high carbon steel specimens. The results of X-ray diffraction, optical microscopy, scanning electron microscopy, and microhardness ...
  • Manganese recovery from leach liquors/residues generated during hydrometallurgical processing of manganese nodules 
    Sanjay, K.; Subbaiah, T.; Anand, S.; Das, R.P. (Proceedings Of The Third (1999) Isope Ocean Mining Symposium, 1999: 246-252)
    Manganese nodule contains 13-26% manganese in oxide/hydroxide form. Copper, nickel and cobalt together vary between 1.5 to 2.5%. Over last several decades processes have been developed for four metals (Cu, Ni, Co and Mn) ...
  • Zinc electrowinning from acidic sulphate solutions. Part III: Effects of quaternary ammonium bromides 
    Tripathy, B.C.; Das, S.C.; Singh, P.; Hefter, G.T. (Journal Of Applied Electrochemistry, 29(10), 1999: 1229-1235)
    The effects of the organic additives cetyltrimethylammonium bromide (CTABr) and tetrabutyl ammonium bromide (TBABr) on the electrowinning of zinc from acidic sulphate solutions were studied in the presence and absence of ...
  • Kinetics and mechanism of MnO2 dissolution in H2SO4 in the presence of pyrite 
    Nayak, B.B.; Mishra, K.G.; Paramguru, R.K. (Journal Of Applied Electrochemistry, 29(2), 1999: 191-200)
    This paper describes a study of the kinetics and mechanism of MnO2 dissolution in H2SO4 in the presence of pyrite through leaching and electrochemical parameters. Manganese(IV) was found to dissolve mainly through reduction ...
  • Role of surface effects in improved dewatering of alumina trihydrate 
    Singh, B.P.; Besra, L.; Prasad, A.R. (Transactions Of The Institution Of Mining And Metallurgy Section C-Mineral Processing And Extractive Metallurgy, 108, 1999: C27-C32)
    The role of surface-chemical phenomena and the physical processes that participate in the dewatering of a suspension of alumina trihydrate were subjected to a systematic investigation, which has increased understanding of ...
  • Thermal and structural study of low grade graphite ore from Shivaganga, India - Its implications in beneficiation process 
    Patnaik, N.; Patil, R.; Saktivelu, R.; Rao, R.B. (Journal Of Thermal Analysis And Calorimetry, 57(2), 1999: 541-549)
    In this paper an attempt has been made to characterize the low grade calcareous graphite ore from Shivaganga region, India. By judicious combination of structural, thermal and chemical analytical techniques, the liberation ...
  • Plasma smelting studies of solid waste effluent from dichromate plant 
    Mukherjee, P.S. (Rewas'99 Global Symposium On Recycling, Waste Treatment And Clean Technology Volume I-III, 1999: 175-181)
    The large quantity of solid waste generated by dichromate plants contains amongst other constituents about 10% to 15% chromium which includes about 1% hexavalent chromium. Thus the problem associated with the effluent ...
