Safety Reports Series No IAEA Scientific and Technical
2002 11 20 The conventional mining and processing of uranium and thorium ores generate large amounts of waste material. Mine operations generate overburden, barren waste rock and mineralized waste. Uranium and thorium mills process the mined material by milling and chemical leaching, and typically produce a residual sand like material

Past experience of environmental, health and safety
2015 10 6 ores contain variable amounts of impurities such as non target toxic metals, fluorine and radionuclides that may be released from the ore during processing into the product or waste streams, and/or represent safety issues to the workers. Past REE mining and processing has led to significant environmental impacts in several non EU countries.
