【摘要】：从南美洲铝土矿资源特征入手,介绍了南美洲主要国家铝土矿资源概况,分析了南美洲铝土矿资源的勘查开发现状,提出了中国铝行业公司勘查开发南美洲铝土矿资源的建议。南美洲铝土矿资源主要分布在巴西、苏里南、圭亚那和委内瑞拉等4个国家,储量为4.35×109t,占世界铝土矿总储量的15.54%,巴西为南美洲最大的铝土矿生产国和出口国。南美洲铝土矿成因类型主要为红土型,主要的铝土矿矿山有53座,主要的铝土矿勘查开发矿业公司有巴西淡水河谷公司、力拓集团、美国铝业公司等15家。巴西的东亚马孙盆地、委内瑞拉的帕尔瓜萨地区和苏里南—圭亚那的沿海平原区为有利的铝土矿勘查开发潜力区。建议中国积极勘查开发南美洲铝土矿资源,巴西的东亚马孙盆地地区是有利的勘查开发投资目标区,加大南美洲铝土矿进口量,积极参与南美洲铝土矿新产能建设。
[Abstract]:Based on the characteristics of bauxite resources in South America, this paper introduces the general situation of bauxite resources in major countries of South America, analyzes the present situation of exploration and development of bauxite resources in South America, and puts forward some suggestions for the exploration and development of bauxite resources in South America by China Aluminum Industry Corporation. The bauxite resources of South America are mainly distributed in four countries, such as Brazil, Suriname, Guyana and Venezuela, with reserves of 4.35 脳 109 t, accounting for 15.54% of the world's total bauxite reserves. Brazil is the largest producer and exporter of bauxite in South America. The genetic types of bauxite in South America are mainly laterite type. There are 53 bauxite mines and 15 Bauxite exploration and mining companies such as Vale of Brazil Rio Tinto Group and Alcoa. The eastern Amazon basin of Brazil, the Parguassa region of Venezuela and the coastal plain of Suriname-Guyana are favorable areas for the exploration and exploitation of bauxite. It is suggested that China should actively explore and develop bauxite resources in South America, and that the eastern Amazon basin of Brazil is a favorable target for investment in exploration and development, increase the import of bauxite from South America, and actively participate in the construction of new production capacity of bauxite in South America.
