Many metallurgical processes have been developed for the extraction of nickel from Sukinda lateritic nickel ore. These processes consume much energy and are also costly. Biological activities of microorganisms have been ...

Highly dispersed fine silica powder has been prepared from the quartzite mineral and petroleum coke by reactive evaporation in the thermal plasma and condensation from the vapour phase. The process made use of an indigenously ...

The presence of turbulence promoters in an electrochemical cell increases the intensity of local turbulence which enhances the limiting current density and hence the mass-transfer coefficient at the transfer surface. The ...

A dinuclear Cu-II compound (Cu(2)L(2)(2+)) with the phenoxide form of N-salicylidine 2-aminomethyIbenzimidazole has been synthesized and characterized on the basis of elemental analysis, UV-visible, IR and variable temperature ...

Cr(III) slowly forms a violet complex with EDTA at pH 3.5 +/- 0.2 under normal conditions. The complex formation can be catalyzed by irradiating the reacting mixture with ultrasonic waves. Quantitative formation of the ...
