Sulphuric Acid Leaching of Manganese Nodules in the ...

Leaching studies were carried out on Indian Ocean manganese nodules using sulphuric acid as the lixiviant. By leaching the nodules with 8 per cent sulphuric acid for 12h at 100C, copper and nickel could be completely extracted along with 50 per cent cobalt and 6.2 per cent manganese.94.2 per cent of the iron was also dissolved. To increase manganese and cobalt extraction, charcoal was used as ...

Leaching of roast-reduced manganese nodules in

2011-10-1  Reduction roast–ammonia leach process developed at NML for extraction of valuable metals from manganese nodules yielded low cobalt recovery (56%), although copper and nickel recoveries were > 90% (Jana et al., 1999b).With an aim to increase the cobalt recovery, a modified NH 3 –(NH 4) 2 CO 3 leaching flow-sheet have been developed for treatment of reduced manganese nodules.

Selective-Reductive Leaching of Manganese from Low

2019-7-31  Selective-reductive leaching of manganese from low-grade manganese ore using tannic acid as a reductant in acidic media was demonstrated by XRD, SEM-EDX characterization, and batch leaching studies at room temperature. The pH change in the liquid phase before and after leaching revealed that selectivity of manganese over iron was due to the hydrolysis of iron. The acidity in the

uranium processing - Leaching Britannica

uranium processing - uranium processing - Leaching: Roasted uranium ores are leached of their uranium values by both acidic and alkaline aqueous solutions. For the successful operation of all leaching systems, uranium must either be initially present in the more stable hexavalent state or be oxidized to that state in the leaching process. Acid leaching is commonly performed by agitating an ore ...
