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 ...
Characterisation of oxidative ammonia leaching behaviour of galena by chemical phase analysis

Rao, K.S.; Muralidhar, J.; Ray, H.S. (Metals Materials And Processes, 9(1), 1997: 25-32)

Leaching of galena is a complex process and, for any process development it is necessary to ensure complete characterisation of oxidation products that appear after leaching. These products form as feed materials to smelters ...
Effect of polymers as dispersing agents on dry grinding of dolomite

Rao, R.B.; Forssberg, E. (Metals Materials And Processes, 9(1), 1997: 49-56)

During ultrafine grinding the particles tend to agglomerate or coat on the media and mill liners. The literature reveals that some of the grinding aids favour to disperse the particles and improve the grinding performance. ...
