Australian iron oregiant Rio Tinto has expressed its gratitude to Western Australia’s Department of Fire and Emergency Services for coordinating the successful search effort to locate a missing capsule lost while in transit from the company’s Gudai-Darri iron ore mine in the Pilbara, Western Australia. Rio Tinto also thanked the specialist search crews from the Australian Defence Force, the Australian Radiation Protection and Nuclear Safety Agency and the Australian Nuclear Science and Technology Organisation, as well as all other support agencies, for their crucial role in the search and recovery efforts.The device involved is an industrial gauge which is commonly used in the mining industry. In this instance it was being used at our Gudai-Darri mine site to measure iron ore feed in the crushing circuit of the fixed plant. The capsule is small (6mm diameter, 8mm long), round and stainless steel, and forms part of a level sensor (gauge) that is used in some fixed plant assets. The gauge, packed by a specialist radioactive materials handler, was collected by a transport contractor from the Gudai-Darri mine site on 12 January.
