项目摘要
Today, the resource depletion is one of the important issues of all over the world. In order to solve this issue, the higher-efficiency techniques for resource recovery from various solid wastes such as ceramics would be required. However, there are no techniques for recovering the variable resources from solid wastes, especially, ceramics, because most ceramics have relatively high stability for heat, mechanical stress and so on. In this research, we investigated on the development of the higher-efficiency techniques for valuable resource from ceramics such as cemented carbides, zirconia and magnet by the hydrothermal nano-process. To show that hydrothermal nano-process technique we proposed is one of key-technologies for solving the resource recovery issues, we investigated the following topics :1.Hydrothermal mechanochemical nano-process2.Hydrothermal oxidation nano-process3.Hydrothermal mineralization nano-processAs a result of this research, we succeeded in recovering valuable res … More ources from the following wastes :1.WO_3 powder and aqueous solution with Co ions were separated from WC-Co cemented carbide cutting tools by the hydrothermal oxidation treatment with acid aqueous solution.2.Zrconia powder for sintering with yttrium was recovered from spent partially stabilized zirconia sintered compact by the hydrothermal and mechanochemical treatment.3.Ferrite particles consisted of Fe and Mn could be recovered from spent toner carrier powder by the hydrothermal oxidation treatment with H_2O_2.4.Neodymium oxalate was recovered from spent Nd-Fe-B permanent sintered magnet by the hydrothermal oxidation treatment with HC1 and oxalic acid.5.Co-A1 composite-oxide could be recovered from spent cathode of the Li-secondary battery by the hydrothermal oxidation treatment.6.Natural minerals could be recovered from wastewaters with various oxo-anions such as boron, fluorine, arsenic, etc. by the hydrothermal mineralization treatment with mineralizer such as hydrated lime and calcium chloride.

如今,资源枯竭已成为全世界面临的重要问题之一。为了解决这个问题,需要更高效的技术来从陶瓷等各种固体废物中进行资源回收。然而,目前还没有从固体废物特别是陶瓷中回收可变资源的技术,因为大多数陶瓷对热、机械应力等具有较高的稳定性。在这项研究中,我们研究了通过水热纳米工艺开发从硬质合金、氧化锆和磁铁等陶瓷中提取宝贵资源的更高效技术。为了表明我们提出的水热纳米工艺技术是解决资源回收问题的关键技术之一,我们研究了以下主题:1.水热机械化学纳米工艺2.水热氧化纳米工艺3.水热矿化纳米工艺作为这项研究的结果,我们成功地从以下废物中回收了有价值的资源……更多来源 :1.通过酸性水溶液水热氧化处理,从WC-Co硬质合金刀具中分离出WO_3粉末和含Co离子的水溶液。2.通过水热和机械化学处理,从废部分稳定氧化锆烧结体中回收钇烧结用氧化锆粉末。3.从废碳粉中回收由Fe和Mn组成的铁素体颗粒 2.4.通过HCl和草酸水热氧化处理废Nd-Fe-B永磁体,回收草酸钕。5.水热氧化处理锂二次电池废正极,回收Co-Al复合氧化物。6.回收天然矿物 采用熟石灰、氯化钙等矿化剂进行水热矿化处理含硼、氟、砷等各种含氧阴离子的废水。较少的
