Different excavation methods are used for exploitation of mineral deposits using underground access. The selection of excavation methodology is based on the nature of orebody and country rock as well as the expected production demand.
Uranium processing
Uranium processing - Leaching, Extraction, Purification: 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.
Underground Uranium Mining
Underground Uranium Mining. As with other types of hard rock mining, there are several methods of extraction. In the case of uranium mining, it strongly depends on the concentration of uranium in the ore. For example, the ore extracted from the Australian Olympic Dam Mine has a concentration of 0.05 %, and most reserves have uranium …
