Elemental analysis of ores in the field conditions using the tagged neutron method
In the practice of mining and ore enrichment it is necessary to determine the elemental content of rock samples taken directly from the quarry, the mine, or on the conveyor belt of the concentration plant. Often, such samples have a large mass (several kg) and a significant size (up to 100 mm). Diamant, LLC have developed a new method and created an installation for determining the elemental content of ore samples of large mass and fineness, which does not need traditional sample preparation. The method is based on the technology of tagged neutrons, which consists in the irradiation of ore by fast neutrons with an energy of 14 MeV. The results of the pilot operation of the plant at the mines of Apatit and Kovdorsky GOK are discussed.
