典型稀土精矿及废渣中清洁提钍工艺研究进展
|
摘要
随着中国不可再生能源的日益紧缺,开发核电新能源对中国可持续发展具有重要意义,钍作为未来核电发展的重要原料,必将成为今后能源发展的新方向,建立钍反应堆可以很大程度上缓解中国对不可再生能源的依赖。中国钍资源储量巨大,在现行的稀土选冶工艺中,钍主要赋存于稀土精矿中或最终进入冶炼废渣,处理不当,不仅对环境造成了放射性污染,同时也造成了钍资源的严重浪费。本文主要对中国近年来典型稀土精矿及废渣中清洁提钍工艺研究进展以及高纯钍的制备进行了综述,并提出了相关建议与意见。
With the decreasing of nonrenewable resources in our country, developing new energy sources of nuclear power is of great significance to the sustainable development of our country. As an important raw material for the future development of nuclear power, thorium will become the new direction of energy development in the future, and the establishment of thorium reactor can greatly ease our country′s dependence on non-renewable energy. China has huge reserves of thorium, in the current rare earth processing and smelting process, thorium mainly occurs in the rare earth concentrate or eventually enters the smelting waste residue, the improper treatment not only causes radioactive pollution, but also causes serious waste of thorium resource. This article mainly summarized the research progresses on the clean extraction of thorium from typical rare earth concentrates and waste residues and the preparation of high purity thorium was reviewed, and some suggestions and measures were puts forward.
