全球铝土矿资源分布特征、勘查开发格局及展望

    Distribution characteristics and exploration & development pattern of global bauxite resources and its prospect

    • 摘要: 铝用途非常广泛,是关乎中国经济社会快速发展的重要基础性原材料之一。全球铝土矿资源丰富,但大部分储量和产量高度集中于少数国家;中国铝土矿储量虽居世界前列,但世界占比仅为2.37%;中国是全球最大的铝土矿消费国,而国内铝土矿产量远不及需求,绝大部分依赖进口,对外依存度较高。为保障铝土矿资源的安全稳定供应,开展全球铝土矿资源的分布特征和勘查开发格局研究,对中国有效布局境外优质铝土矿资源的勘查开发合作和矿业投资具有重要意义。研究结果表明:①全球80%以上的铝土矿储量集中于几内亚、澳大利亚、巴西等9个国家;②亚洲和中国是全球大型-超大型铝土矿床数量最多的地区和国家;③拉丁美洲铝土矿勘查开发程度相对较高,大洋洲、非洲勘查开发程度相对较低;④近十年全球勘查新发现的重要铝土矿床主要分布在澳大利亚和几内亚;⑤全球铝土矿勘查热点国家主要为澳大利亚、几内亚和喀麦隆,全球铝土矿勘查增量也主要来自这三个国家;⑥澳大利亚、几内亚、中国等三国为全球贡献了70%的铝土矿年产量,全球前十大铝土矿矿业公司贡献了近40%的铝土矿年产量;⑦几内亚、澳大利亚、印度尼西亚等三国是全球主要的铝土矿出口国,中国是全球最大的铝土矿进口国;⑧全球铝土矿矿业并购较少,且高度集中于澳大利亚、牙买加两国。展望未来,全球铝土矿勘查找矿潜力和开发潜力巨大,全球铝土矿产量与需求量可能会持续上升,中国将持续为世界最大的铝土矿、原铝、精炼铝消费国。

       

      Abstract: Aluminum is widely used in many fields, and is one of the important basic raw materials related to the rapid development of China’s economy and society. Global bauxite resources are rich, but the global reserves and production of bauxite are distributed in a few countries. The bauxite reserve of China is ranked in the top position in the world, but the share in the world is only 2.37%. At present, China is the largest consumer of bauxite in the world. The production of bauxite is much less than the demand in China. China imports a lot of bauxite every year, and has a high degree of dependence on import from other countries. The research on the distribution characteristics and exploration & development pattern of global bauxite resources has great significance for the effective layout of exploration & development cooperation and mining investment of overseas high-quality bauxite resources. The research results show that ①more than 80% of bauxite reserves are distributed in 9 countries such as Guinea, Australia and Brazil in the world. ②Asia and China have the largest number of large-super large bauxite deposits in the world. ③The degree of exploration and development of bauxite is relatively high in Latin America, and is relatively low in Oceania and Africa in the world. ④The newly discovered bauxite deposits by exploration are distributed in Australia and Guinea. ⑤Australia, Guinea and Cameroon are the hotspot countries of global bauxite exploration in the world, and also are the major countries with the increase of reserves and resources of bauxite. ⑥The 70% of annual bauxite production in the world is distributed in Guinea, Australia and Indonesia. The largest top 10 companies of bauxite exploration & development produced the 40% of annual bauxite production. ⑦Guinea, Australia and Indonesia are the major exporters of bauxite in the world. China is the largest importers of bauxite. ⑧The mergers and acquisitions of bauxite are few, and highly concentrated in Australia and Jamaica. Looking forward to the future, the exploration prospecting potential and development potential of bauxite is huge. The production and demand of bauxite will continue to rise in the world. China will continue to be the largest consumer of bauxite, aluminum and refined aluminum in the world.
