| The ‘Nuclear Boron Ore’ Viewed from the Angle of Geochemistry |
| Under the severe condition of increasing domestic demand for nuclear boron, some enterprises claimed that a “nuclear boron ore” was found in Ali, west Tibet. In view of the proposal and significance of this claim, the present paper gives a review of the characteristics of abundance-10B in major boron ore deposits in the world. Based on a comparative analysis of boron isotopes of the boron ore deposits in China, the authors converted the boron isotopic geochemical parameter into abundance index of 10B in nuclear boron. On the basis of the general view of the worldwide 10B resources, the authors hold that “nuclear boron ore” is a wrong concept, because the absolute abundance of 10B is evaluated by the relative abundance of boron isotopic geochemical parameter. It is therefore proposed that the key to the needs of nuclear boron lies in developing 10B isotope separation techniques with high efficiency, low consumption and environmental protection. |
