The flotation studies of non-coking coal fines containing 37.7% ash were carried out. The variables studied were pH, collector, frother, modifier (sodium silicate) and coal size. Experiments were carried out using 2(5) ...

The effects of perfluorobutyric acid, perfluoroheptanoic acid and perfluorooctanoic acid, in the presence and absence of antimony(III), on the cathodic current efficiency, power consumption and polarisation behaviour of ...

Effect of aluminum substitution in barium hexaferrite was studied following the hydrothermal precipitation-calcination techniques. It was attempted to prepare aluminum-substituted barium hexaferrites with compositions ...

Hydrated basic aluminium sulfates (BAS) are of great importance as precursor material for the preparation of activated and high pure calcined aluminas. Low bulk density category BAS powders have superior quality over higher ...

Nanoparticles of Ni1-xZnxFe2O4 (x=0.0, 0.25, 0.50, 0.75, and 1.0) in the size range of 6-12 nm have been synthesized by chemical precipitation followed by hydrothermal treatment. A strong correlation between the particle ...
