Nov 10, 2017 This study explored the processing of chalcopyrite ore through heap leaching followed by flotation. Crushed and agglomerated chalcopyrite ore was subjected to bacterially-assisted leaching at ambient temperature in columns that ranged in height from 1 m to 5 m. 50% extraction was obtained after 16 months.Chalcopyrite leaching was affected only by time, not irrigation rate, acid delivery rate

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
