Carrying capacity in flotation columns

Sastri, S.R.S. (Minerals Engineering, 9(4), 1996: 465-468)

The equation proposed by Espinosa-Gomez et.al. for the carrying capacity in flotation columns is revised to give better fit to the data. Flotation columns are found to be normally operated around 60% of their maximum ...
Densities and viscosities of NiSO4-H2SO4-H2O system

Das, K.C.; Panda, D.; Singh, S.K. (Physics And Chemistry Of Liquids, 32(2), 1996: 123-126)

Densities and kinematic viscosity data for the ternary system NiSO4-H2SO4-H2O were determined over a wide range of concentrations (0.93 - 1.36 mols. dm(-3)) and temperatures (20 degrees C to 60 degrees C). The results were ...
Extraction of iron(III) at macro-level concentrations using TBP, MIBK and their mixtures

Reddy, B.R.; Sarma, P.V.R.B. (Hydrometallurgy, 43(1-3), 1996: 299-306)

Iron(III) extraction has been carried out at about 1 molar concentration from hydrochloric acid solutions using tri-n-butyl phosphate, methyl-iso-butyl ketone and their mixtures as solvents, Extraction increases with ...
Improved ionic mass transfer in an electrochemical cell in presence of turbulence promoters

Subbaiah, T.; Venkateswarlu, P.; Das, R.P.; Raju, G.J.V.J. (Hydrometallurgy, 42(1), 1996: 93-102)

In industrial operations, reduction in equipment size can increase productivity, lower energy inputs and improve purity of the product. The presence of turbulence promoters in an electrochemical cell can increase the ...
Behaviour of cobalt during precipitation of manganese from the NH3-(NH4)(2)SO4-Mn-O-2 system

Mohanty, S.; Ghosh, M.K.; Chakravortty, V.; Anand, S. (Hydrometallurgy, 42(3), 1996: 357-366)

A detailed study was made on cobalt losses during precipitation of manganese from the NH3-(NH4)(2)SO4-O-2 system. Various parameters were changed during this study: the concentration of ammonia and ammonium sulphate; oxygen ...
Coupled transport of Zn(II) through a supported liquid membrane containing bis(2,4,4-trimethyl pentyl) phosphinic acid in kerosene .1. A model for the rate process involving binary and ternary complex species (vol 105, pg 217, 1995)

Kanungo, S.B.; Mohapatra, R. (Journal Of Membrane Science, 118(2), 1996: 303-303)
Regional research laboratory (CSIR), Bhubaneswar, India: A brief report on activities during 1995

Das, R.P. (Hydrometallurgy, 43(1-3), 1996: 391-392)
Thermogravimetric and XRD studies on iron compounds precipitated from Fe(II)-SO4-NH3-O-2 system

Das, R.P.; Anand, S. (International Journal Of Mineral Processing, 48(3-4), 1996: 159-168)

X-ray diffraction and thermogravimetric studies have been carried out on iron precipitates obtained at different time intervals from Fe(II)-SO4-NH3-O-2 system. Depending on the experimental conditions amorphous and crystalline ...
Effect of Fe(III) during copper electrowinning at higher current density

Das, S.C.; Krishna, P.G. (International Journal Of Mineral Processing, 46(1-2), 1996: 91-105)

The effect of Fe(III) during copper electrowinning was studied using an open channel cell. The interaction of various electrolysis parameters due to the presence of Fe(III) in the copper sulphate electrolyte was evaluated, ...
Behaviour of LIX 64N during copper electrowinning from a bath containing Fe3+

Pradhan, N.; Krishna, P.G.; Das, S.C. (International Journal Of Mineral Processing, 48(3-4), 1996: 217-224)

The behaviour of LIX 64N during copper electrowinning from sulphate bath containing Fe3+ was investigated. The results show that LIX 64N alone does not affect either current efficiency or nature of copper deposit. But when ...
