This paper examines galvanic interaction of the MnO2-FeS2 couple through polarization and leaching studies. Large galvanic currents, observed between electrodes of this couple, increase further with an increase in H+ ...

The mineral composition, mineralogy and surface properties of manganese nodules and their implications in the catalytic activity are described. The high surface area (90-400m(2) nodules increases on calcination up to 400 ...

Flotation column is one of the most promising type of equipments which is going to replace the existing notation cell in industrial sector. Problems encountered in columns when applied in heavy and coarser particles notation ...

The atomic and structural contributions proposed by Schroeder (Partington, 1949) for estimating the molar volume at the normal boiling point have been revised to improve the accuracy. Extensive testing with data for 163 ...
