Recovery of nickel from lateritic nickel ore using Aspergillus niger and optimization of parameters

Mohapatra, S.; Pradhan, Nilotpala; Mohanty, Swati; Sukla, L.B. (Minerals Engineering, 22(3), 2009: 311-313)

The present study deals with the extraction of nickel from lateritic nickel ore of Sukinda mines, Orissa, through microbial leaching using Aspergillus niger. The presence of significant metals in oxidic nickel ores, are ...
Electrowinning of zinc from sulphate solutions in the presence of perfluoroglutaric acid

Sarangi, C.K.; Tripathy, B.C.; Bhattacharya, I.N.; Subbaiah, T.; Das, S.C.; Mishra, B.K. (Minerals Engineering, 22(14), 2009: 1266-1269)

This paper deals with the effect of perfluoroglutaric acid in the presence and absence of antimony(III) on the cathodic current efficiency, energy consumption and polarisation behaviour of the cathode during electrowinning ...
Artificial neural network based system identification and model predictive control of a flotation column

Mohanty, Swati (Journal Of Process Control, 19(6), 2009: 991-999)

The paper describes the design of a neural network based model predictive controller for controlling the interface level in a flotation column. For the system identification, the tailings valve opening is subjected to a ...
A preliminary study on the adsorptive removal of Cr(VI) using seaweed, Hydrilla verticillata

Baral, S.S.; Das, N.; Chaudhury, G.R.; Das, S.N. (Journal Of Hazardous Materials, 171(1-3), 2009: 358-369)

The Cr(VI) adsorption efficiency of the seaweed, Hydrilla verticillata, was studied in batches. The adsorbent was characterized using SEM, BET surface area analyzer, Malvern particle size analyzer, EDAX and FT-IR. Cr(VI) ...
Synthesis of Mg(II) doped goethite and its cation sorption behaviour

Mohapatra, M.; Rout, K.; Anand, S. (Journal Of Hazardous Materials, 171(1-3), 2009: 417-423)

Modified goethite samples were prepared with Mg(II) content varying in the range of 0-1.36%. A typical TEM of Mg(II) doped sample showed needle shaped goethite particles having 10-30 nm width and 100-400 nm length. Sorption ...
Self-organized transformation to polyaniline nanowires by pulsed energetic electron irradiation in a plasma focus device

Mohanty, S.R.; Neog, N.K.; Rawat, R.S.; Lee, P.; Nayak, B.B.; Acharya, B.S. (Physics Letters A, 373(22), 2009: 1962-1966)

An ingenious method for fabricating network of polyaniline nanowires at room temperature in microsecond timescale is demonstrated by using the pulsed electron beam of a plasma focus device. The electron beam of the plasma ...
Extraction of cadmium from dilute solution using supported liquid membrane

Parhi, P.K.; Das, N.N.; Sarangi, K. (Journal Of Hazardous Materials, 172(2-3), 2009: 773-779)

The extraction efficiencies of three phosphoric acid derivatives (D2EHPA, PC-88A and Cyanex 272) for Cd in supported liquid membrane (SLM) have been reported. The equilibrium study indicated the release of two moles of ...
Studies on sorption of some geomaterials for fluoride removal from aqueous solutions

Sujana, M.G.; Pradhan, H.K.; Anand, S. (Journal Of Hazardous Materials, 161(1), 2009: 120-125)

In the present study the defluoridation capacities of some of the naturally occurring materials like low and high iron containing lateritic ores, overburden from chromite mines of Orissa Mining Corporation (OMC) and Tata ...
Removal of Cr(VI) by thermally activated weed Salvinia cucullata in a fixed-bed column

Baral, S.S.; Das, N.; Ramulu, T.S.; Sahoo, S.K.; Das, S.N.; Chaudhury, G.R. (Journal Of Hazardous Materials, 161(2-3), 2009: 1427-1435)

The present study evaluates the feasibility of using a thermally activated fresh water weed in removing Cr(VI) from wastewater through column studies. The effect of flow rate, bed height and Cr(VI) concentration of the ...
Sorption behavior of Pb(II) and Cd(II) on iron ore slime and characterization of metal ion loaded sorbent

Mohapatra, M.; Rout, K.; Mohapatra, B.K.; Anand, S. (Journal Of Hazardous Materials, 166(2-3), 2009: 1506-1513)

The present investigation evaluates the sorption effectiveness of Pb(II) and Cd(II) ions on iron ore slime (IOS) obtained from Jindal Steel Ltd., Vijayanagaram, India. The sorption followed pseudo-second-order kinetics for ...
