  • Production of eta-alumina from waste aluminium dross 
    Das, B.R.; Dash, B.; Tripathy, B.C.; Bhattacharya, I.N.; Das, S.C. (Minerals Engineering, 20(3), 2007: 252-258)
    Processing of aluminium dross is one of the most challenging tasks because of its toxic nature. The dross generated while melting at various facilities is generally remelted with salts to recover residual metal values. The ...
  • An overview of utilization of slag and sludge from steel industries 
    Das, B.; Prakash, S.; Reddy, P.S.R.; Misra, V.N. (Resources Conservation And Recycling, 50(1), 2007: 40-57)
    Significant quantities of sludge and slag are generated as waste material or byproduct every day from steel industries. They usually contain considerable quantities of valuable metals and materials. It is generally possible ...
  • Leaching of manganese ores using sawdust as a reductant 
    Hariprasad, D.; Dash, B.; Ghosh, M.K.; Anand, S. (Minerals Engineering, 20(14), 2007: 1293-1295)
    In this study sawdust was used as reductant for sulphuric acid leaching of manganese ore. Effects of pulp density, amount of acid, temperature, particle size of ore and amount of sawdust were studied. Manganese extraction ...
  • Mn(III) oxide pillared titanium phosphate (TiP) for catalytic deep oxidation of VOCs 
    Das, D.P.; Parida, K.M. (Applied Catalysis A-General, 324, 2007: 1-8)
    A series of trinuclear acetato complex of Mn(III) intercalated TiP was successfully prepared by ion-exchange process, by varying the wt% of Mn(III) and activated at various temperatures. The calcined and uncalcined samples ...
  • Structural properties and catalytic oxidation of benzene to phenol over CuO-impregnated mesoporous silica 
    Parida, K.M.; Rath, D. (Applied Catalysis A-General, 321(2), 2007: 101-108)
    A series of copper catalysts supported on mesoporous molecular sieves MCM-41 with copper loading varying from 2 wt% to 10 wt% were synthesized by impregnation method using aqueous copper nitrate solution as the precursor. ...
  • Effect of additives on the microstructure of porous alumina 
    Bhattacharjee, S.; Besra, L.; Singh, B.P. (Journal Of The European Ceramic Society, 27(1), 2007: 47-52)
    Protein forming, a direct consolidation technique for shaping of powders into a rigid body, use globular protein as gelling agent, which makes the process environment friendly. The present paper combines foaming and gelling ...
  • Microbial extraction of nickel from Sukinda chromite overburden by Acidithiobacillus ferrooxidans and Aspergillus strains 
    Mohapatra, S.; Bohidar, S.; Pradhan, Nilotpala; Kar, R.N.; Sukla, L.B. (Hydrometallurgy, 85(1), 2007: 1-8)
    In this study, the recovery of nickel from a low-grade chromite overburden was attempted by employing two fungal strains, Aspergillus niger and Aspergillus fumigatus, and a mixed culture of mesophilic acidophiles (predominantly ...
  • Genetic algorithms - A novel technique to optimize coal preparation plants 
    Gupta, V.; Mohanty, M.; Mahajan, A.; Biswal, S.K. (International Journal Of Mineral Processing, 84(1-4), 2007: 133-143)
    A coal preparation plant typically operates with multiple cleaning circuits based on the particle size distribution of run-of-mine coal. Clean coal product from a plant commonly has to satisfy multiple product quality ...
  • Studies on sorption of Cd(II) on Tata chromite mine overburden 
    Mohapatra, M.; Anand, S. (Journal Of Hazardous Materials, 148(3), 2007: 553-559)
    Chromite mine overburden containing iron as oxide/hydroxide, a waste material generated in chromite mines was used as sorbent for cadmium. The iron content of material was 43.75% with a specific surface area of 50.8 m(2)/g. ...
  • Effect of temperature and alumina/caustic ratio on precipitation of boehmite in synthetic sodium aluminate liquor 
    Dash, B.; Tripathy, B.C.; Bhattacharya, I.N.; Das, S.C.; Mishra, C.R.; Pani, B.S. (Hydrometallurgy, 88(1-4), 2007: 121-126)
    In Bayer process gibbsite (alumina trihydrate, Al(2)O(3).3H(2)O) is precipitated from sodium aluminate liquor for production of alumina by calcination. Precipitation of boehmite or alumina monohydrate (Al(2)O(3).H(2)O) is ...
