  • Mining Milling

    In some circumstances, ore may be mined by in situ recovery, a process that dissolves the uranium while still underground and then pumps a uraniumbearing solution to the surface. Open pit mining. When uranium ore is found near the surface, generally less than 100 metres deep, it is typically extracted by open pit mining.

  • Nuclear Fuel Cycle Overview

    The nuclear fuel cycle starts with the mining of uranium and ends with the disposal of nuclear waste. With the reprocessing of used fuel as an option for nuclear energy, the stages form a true cycle. To prepare uranium for use in a nuclear reactor, it undergoes the steps of mining and milling, conversion, enrichment and fuel fabriion.
