  • Characterization and kinetic study on ammonia leaching of complex copper ore 
    Baba, A.A.; Ghosh, M.K.; Pradhan, S.R.; Rao, D.S.; Baral, A.; Adekola, F.A. (Transactions Of Nonferrous Metals Society Of China, 24(5), 2014: 1587-1595)
    Ammonia leaching kinetics of a complex Cu-ore assaying 8.8% Cu and 36.1% Fe was examined. Mineralogical characterization indicated that the major phase of the ore was siderite with chalcopyrite as the major sulfide mineral. ...
  • Influence of band thickness of banded hematite quartzite (BHQ) ore in flotation 
    Rath, S.S.; Sahoo, H.; Das, S.K.; Das, B.; Mishra, B.K. (International Journal Of Mineral Processing, 130, 2014: 48-55)
    Hematite and quartz present in banded iron ore are intimately associated with one another and require fine grinding for the liberation of mineral particles. The influence of the thickness of bands on the liberation and ...
  • Copper electrodeposition from sulfate solutions-Effects of selenium 
    Baral, A.; Sarangi, C.K.; Tripathy, B.C.; Bhattacharya, I.N.; Subbaiah, T. (Hydrometallurgy, 146, 2014: 8-14)
    The upshot of the presence of selenium in the electrolytic solution as an impurity over a concentration range of 0 to 1000 mg dm(-3) during the electrodeposition of copper from sulfate solutions has been investigated in ...
  • Studies on extraction of potassium values from nepheline syenite 
    Jena, S.K.; Dhawan, N.; Rao, D.S.; Misra, P.K.; Mishra, B.K.; Das, B. (International Journal Of Mineral Processing, 133, 2014: 13-22)
    Nepheline syenite is a complex rock consisting of different mineral phases such as nepheline, alkali feldspar, and biotite. It is a promising source for the recovery of potassium and alumina values. India is importing most ...
  • Ultrasonic assisted cleaning of high sulphur Indian coals in water and mixed alkali 
    Saikia, B.K.; Dutta, A.M.; Saikia, L.; Ahmed, S.; Baruah, B.P. (Fuel Processing Technology, 123, 2014: 107-113)
    The present investigation reports the application of ultrasonic energy (20 kHz) to few high sulphur Indian coal samples in aqueous and mixed alkali media (1:1 KOH and NaOH) for removal of sulphur and ash for industrial ...
  • Preparation of layered nickel aluminium double hydroxide from waste solution of nickel 
    Barik, G.; Padhan, E.; Dash, B.; Sarangi, K.; Subbaiah, T. (Minerals Engineering, 69, 2014: 107-112)
    The separation of nickel has been carried out from a waste solution containing 3.18 g/L Ni with other impurities such as Fe, Zn, Cu and As. Iron was removed by precipitation and Cu and Zn were removed by solvent extraction ...
  • Density functional calculations of amines on the (101) face of quartz 
    Rath, S.S.; Sahoo, H.; Das, B.; Mishra, B.K. (Minerals Engineering, 69, 2014: 57-64)
    This study illustrates a density functional theory (DFT) based approach to design the amine collectors with regards to their interaction with the quartz surface. Mechanism of interaction of primary aliphatic amines and ...
  • Tailoring of optical and wetting properties of sputter deposited silica thin films by glancing angle deposition 
    Sarkar, S.; Pradhan, Siddhartha Kumar (Applied Surface Science, 290, 2014: 509-513)
    Synthesis of silica thin films by RF magnetron sputtering using glancing angle deposition (GLAD) has been reported here. Films deposited at four different oblique angles (45 degrees, 60 degrees, 75 degrees, 85 degrees) ...
  • Effect of high magnesium content on microstructure of Al-7Si alloy 
    Mandal, A.; Chippa, N.; Jayasankar, K.; Mukherjee, P.S. (Materials Letters, 117, 2014: 168-170)
    A new class of ternary Al-7Si-xMg alloys was developed with improved microstructure consisting of fine spheroidal Mg2Si and eutectic Si particles dispersed in alpha-Al. The studies show that Mg and Sr have a modification ...
  • Investigations on structural, optical and thermoelectric parameters of spray deposited bismuth selenide thin films with different substrate temperature 
    Anwar, Sharmistha; Anwar, Shahid; Mishra, B.K.; Singh, S.K. (Materials Chemistry And Physics, 148(1-2), 2014: 230-235)
    A series of Bi2Se3 films was deposited at different substrate temperature in 150-500 degrees C temperature range using spray pyrolysis technique, in order to study the effect of substrate temperature on structural and ...
