manganese processing | britannica

For applications in which pure manganese is preferred, manganese ores are roasted to obtain an MnO calcine, and this is dissolved in sulfuric acid to form a manganous sulfate solution. The addition of ammonia precipitates iron and aluminum, and the addition of hydrogen sulfide precipitates arsenic, copper, zinc, lead, cobalt, and molybdenum… Read more

Jul 27, 2015 · Since less ozone is required in ozonation, compared to UV-ozonation, to achieve acceptable removal of manganese, the ozonation process is more preferable. It should be noted that the application of ozone alone in degradation of manganese is more effective than UV-ozonation while the initial concentration of ozone is below a certain level (9.8 ppm at reaction time interval of 20 min)… Read more

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… Read more
