高岭土尾矿高效开发利用的新进展

New Progress on High-efficiency Exploitation and Utilization of Kaolin Tailings

摘要: 高岭土尾矿是高岭土矿选矿过程中产生的固体废弃物,随着排放量越来越大,所产生的问题也日趋严重。阐述了我国高岭土尾矿的现状、特点及高岭土尾矿高效利用的重要性,高岭土尾矿中有价成分回收再利用的研究进展以及高岭土尾矿在建筑材料、陶瓷玻璃制品、无机高分子絮凝剂等矿物材料中的应用情况。阐述了二次资源的高效开发利用与经济发展问题、环境问题密切相关,并且具有综合的社会效益、经济效益和生态环境效益。从资源有效利用和提升资源利用价值的角度,指出了未来高岭土尾矿的高效开发利用与技术开发的发展方向,而未来走尾矿产业化道路已经成为实现我国矿产资源可持续发展的必然选择。

Abstract: Kaolin tailing is the solid waste produced during the course of beneficiation.As the emission becomes more,serious problems become more.In this paper the current situation and characteristics of kaolin tailings were represented,the importance of its high-efficiency utilization was stated,the research progress on its valuable components recycling and its application in mineral materials such as building materials,ceramic and glass products and polymeric flocculants were introduced systematically.At the same ...
