项目摘要
Thorium as a common radionuclide in some ore minerals, mine wastes and mine tailings poses a serious risk to the environment on the one hand but represents a potential source of this strategic material for the thorium fuel cycle that is becoming increasingly viable in recent years. Therefore, extraction of thorium as a byproduct from ores or waste materials not only has environmental benefits but also is of economic value. Three types of materials that contain elevated thorium contents are: (1) anhydrite- and gypsum-rich tailings stemming from the extraction of rare earth elements from monazite and bastnaesite ores; (2) ferroniobium slag from smelting of pyrochlore concentrates to produce ferroniobium alloy and (3) titanium slag (used for TiO2 pigment) from smelting of ilmenite concentrates extracted from heavy mineral sands. Extraction of thorium as a byproduct and recovery of thorium from mine wastes for the thorium fuel cycle both require detailed knowledge about the distribution, speciation and uptake mechanisms of thorium in host materials. The present study, in collaboration with Rio Tinto Fer et Titane of Sorel-Tracy, Quebec, is designed to use several state-of-the-art analytical techniques (e.g., microbeam synchrotron X-ray fluorescence mapping, synchrotron X-ray absorption spectroscopy, and electron paramagnetic resonance spectroscopy) to investigate the distribution, speciation and uptake mechanisms of thorium in selected titanium slags and ilmenite concentrates, with applications to both minimizing radiation risks to the environment and potential development of new techniques to extract this material for the thorium fuel cycle. The specific objectives of the proposed project include: 1) systematic study on the distribution of thorium in titanium slags and ilmenite concentrates, 2) detailed structural study on the speciation and uptake mechanisms of thorium in titanium slags and ilmenite concentrates, and 3) preliminary experiments to extract thorium from titanium slags and ilmenite concentrates. This project of combined basic and applied research provides an excellent training opportunity for one PhD student (Kamil Chadirji-Martinez) and one undergraduate research assistant at the University of Saskatchewan.
钍作为某些矿石矿物、矿山废物和尾矿中的一种常见放射性核素,一方面对环境构成严重风险,但也是近年来日益可行的钍燃料循环的这一战略材料的潜在来源。因此,从矿石或废料中提取钍作为副产品不仅具有环境效益,而且具有经济价值。钍含量高的三种材料是:(1)从独居石和氟碳铈矿中提取稀土元素产生的富含硬石膏和石膏的尾矿;(2)熔炼烧绿石精矿生产铌铁合金产生的铌铁炉渣;(3)熔炼从重矿砂中提取的钛铁矿精矿产生的钛渣(用于二氧化钛颜料)。提取作为副产品的钍和从矿山废物中回收钍用于钍燃料循环,都需要详细了解钍在主体材料中的分布、形态和吸收机制。本研究与魁北克Sorel-Tracy的Rio Tinto Fer et Titane合作,旨在使用几种最先进的分析技术(例如,这些技术包括微束同步加速器X射线荧光绘图、同步加速器X射线吸收光谱和电子顺磁共振光谱),以调查选定的钛渣和钛铁矿精矿中钍的分布、形态和吸收机制,其应用既可最大限度地减少对环境的辐射风险,也可开发为钍燃料循环提取这种材料的新技术。该项目的具体目标包括:1)系统研究钛渣和钛精矿中钍的分布,2)详细研究钛渣和钛精矿中钍的形态和吸收机制,3)从钛渣和钛精矿中提取钍的初步实验。这个基础和应用研究相结合的项目为萨斯喀彻温大学的一名博士生(Kamil Chadirji-Martinez)和一名本科生研究助理提供了极好的培训机会。
