Characterisation and beneficiation studies of charge chrome slag

Das, B.; Mohanty, J.K.; Reddy, P.S.R.; Ansari, M.I. (Scandinavian Journal Of Metallurgy, 26(4), 1997: 153-157)

Background: The slag generated at Indian charge chrome plants is associated with various amounts of charge chrome values. It has been established that charge chromes present in the slag are magnetic in nature. Hence, ...
Semidiurnal variation of some physico-chemical parameters in the Mahanadi estuary, east coast of India

Das, J.; Das, S.N.; Sahoo, R.K. (Indian Journal Of Marine Sciences, 26(3), 1997: 323-326)

Some physico-chemical parameters Like water temperature, pH, suspended solid, salinity, dissolved oxygen, NO2-, NO3-, NH3 and PO43- were investigated at the Mahanadi estuary under varying tidal conditions during monsoon, ...
Effect of nickel on the catalytic activity of SO42-/ZrO2 for the isomerisation of n-butane

Parida, K.M.; Pattnayak, P.K. (Indian Journal Of Chemistry Section A-Inorganic Bio-Inorganic Physical Theoretical & Analytical Chemistry, 36(7), 1997: 617-620)

A series of SO42-/ZrO2 samples with varying sulphur (SO42-) concentration from 1.2 to 4.2 wt% and Ni promoted SO42-/ZrO2 samples have been prepared by controlled impregnation method and characterised by different techniques. ...
Properties of carboxymethylcellulase (endo-1,4-beta-glucanase) from Bacillus sp. isolated from the marine sponge (Axinella sp.)

Mohapatra, B.R. (Indian Journal Of Marine Sciences, 26(3), 1997: 292-296)

The bacterium Bacillus sp. isolated from the marine sponge Axinella sp. produces alkaline serine type endoglucanase. The enzyme was most active at pH 8.0 and 55 degrees C. The activation and deactivation energies, calculated ...
Spherical agglomeration of scheelite fines with amphoteric collector

Rao, G.V. (Metals Materials And Processes, 9(1), 1997: 57-63)

Amphoteric collector, Medialan KA, which contains both positive and negative functional groups in the same molecule was studied as a surfactant for spherical agglomeration of scheelite fines from a synthetic binary mixture ...

Defluorination of waste waters

Sujana, M.G.; Thakur, R.S.; Das, S.N.; Rao, S.B. (Asian Journal Of Chemistry, 9(4), 1997: 561-570)
Effect of roasting and ammonia leaching on the mineralogy of multimetal sulphides

Rao, K.S.; Ray, H.S. (Metals Materials And Processes, 9(1), 1997: 33-44)

This paper describes the significance of mineralogy applied to metal extraction from complex sulphide ores of Ambaji (Ambamata) origin, Gujarat, India. The textural associations of various sulphide minerals in the ore as ...
Effect of oxidative degradation of coal on ball milling of basic slag

Rao, R.B.; Singh, B.P. (Metals Materials And Processes, 9(1), 1997: 45-48)

On an average the steel plants of India generate the slag about 2.5 x 10(6) tonnes/annum and dumped as a waste material. This slag containing P2O5, 2% to 8% and CaO, 30% to 50%, is suitable after comminution to d(95), 0.063 ...
