Complex system of geochemical variables obtained from manganese ores of Balaghat mine, M.P., is simplified by using R-mode factor analysis of correlation matrix. Eighteen major oxides and trace elemental variable have been ...

Leaching of beneficiated lateritic chromite overburden sample was carried out at 250-260 degrees C with 0.3-0.4 g H2SO4/g of material. It was observed that in laboratory scale experiments, similar to 67% nickel could be ...

Ammoniojarosite samples were prepared at 368 and 483 K. The XRD patterns of these samples were identical, showing sharp peaks corresponding to d lines of reported ammoniojarosite. TG-DTA curves show that the decomposition ...

Since many divalent metal ions form more than one complex species with organic extractants, the transport process of such metal ions through a supported liquid membrane (SLM) containing similar extractants as carriers, may ...

Nickel losses have been observed from leach liquors obtained during extraction of metal values from ocean nodules using ammonium sulphite. Studies have been carried out to establish the reasons for such losses. Behaviour ...
