The Uranium ore treatment plant at Jaduguda, India, recovers copper, nickel and molybdenum as byproducts before the bulk flotation tailings are subjected to leaching to recover uranium values. The recoveries of these sulfide ...

A series of experiments were undertaken with four commercial polyelectrolytes to optimise coagulation treatment of water for turbidity removal. The optimum pH range and concentration of reagents in clarification as well ...

The paper presents a theoretical analysis of MnO2-FeS2 dissolution in acidic media. It is assumed that MnO2 and FeS2 dissolve through the operations of MnO2/Fe2+ and FeS2/Fe3+ corrosion couples. Al the mixed potential E-m, ...

The ion-exchange properties of amorphous aluminum phosphate have been studied in aqueous electrolyte solutions of KCl over a temperature range of 300-320 K. The data were explained by the law of mass action. Sorption of ...
