| 铝土矿作为一种战略性大宗矿产资源，是国家经济建设的重要物质基础，在保障氧化铝行业供应链安全稳定和健康发展中具有重要作用。铝土矿作为一种战略性大宗矿产资源，是国家经济建设的重要物质基础，在保障氧化铝行业供应链安全稳定和健康发展中具有重要作用。本文介绍了国内铝土矿资源现状、进口情况以及资源类型，分析了中国铝土矿资源的主要特点以及资源开发过程中存在的问题。针对我国铝土矿资源储量低且品质差的特征，从铝土矿选矿脱硅与铝土矿选矿脱硫两个方面重点介绍了铝土矿选矿技术的研究现状及存在的问题，并指出了未来铝土矿选矿技术研究的重点领域。同时建议在持续开发利用国内低品位复杂铝土矿资源的基础上，依靠国家“一带一路”战略，优化铝土矿资源进口方式，改变铝土矿资源进口来源比较集中的局面，使铝土矿资源进口多元化，进而构建中国铝土矿资源全球安全保障体系，从根本上提升中国铝土矿资源保障能力。 |

| As a kind of strategic bulk mineral, bauxite is an important material basis for national economic con.struction, and plays an important role in ensuring the safety, stability and healthy development of the supply chain of alumina industry. This article presents the current status of domestic bauxite resources, import circumstances,and resource types. It also analyzes the main characteristics of bauxite resources in our country and the issues exist.ing in the process of resource development. In light of the characteristics of low reserves and poor quality of bauxiteresources in China, this article mainly introduces the research status and existing problems of bauxite beneficiationtechnology from the two aspects of silica removal in bauxite beneficiation and sulfur removal in bauxite beneficia.tion, and indicates the key areas for future research on bauxite beneficiation technology. Simultaneously, it is pro.posed that on the basis of the continuous development and utilization of domestic low-grade and complex bauxite re.sources, we should rely on the national "Belt and Road Initiative" to optimize the import mode of bauxite resources,alter the relatively concentrated situation of bauxite resource import sources, diversify the import of bauxite re.sources, construct a global security guarantee system for China′s bauxite resources, and fundamentally enhanceChina′s guarantee capacity for bauxite resources. |
