leach tanks for leaching manganese

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 …

  • Cleaning leaching a plating tank

    Jan 11, 2021 Normally I would leach the tanks with 1-2% sulfuric acid, and try to get some heat to it, 140 F if/when possible. What are some options used in the industry? I thought about 35% hydrogen peroxide @ 1-2 mls/litre to add to the sulfuric. After leaching, ph adjust to 6-9 in the tank, then send the waste water to waste treatment. Regards, Eric Bogner
