摘　　要：锰是全球重要的基础性大宗原料矿产,同时也被世界主要经济体列为关键矿产资源。全球锰矿的成矿类型可以分为海相沉积型、变质型、火山(热液)—沉积型、热液型、表生型5种类型,元古宙和新生代是主要的成矿时期。全球锰矿分布不均,主要集中于南非、澳大利亚、巴西、乌克兰、加蓬、中国、印度和加纳等国,而优质高品位锰矿主要集中于南非、澳大利亚、巴西和加蓬,同时这4个国家也是我国锰矿资源的主要进口对象。本文对上述4国及我国新疆地区的锰矿床特征进行了梳理、总结,并对锰矿全球供需格局进行了分析。近年来,全球锰矿贸易量稳步上升,南非、加蓬、巴西和加纳对我国锰矿出口量增长明显。目前,全球主要锰矿资源国勘查处于低谷期,锰矿市场相对冷清,价格相对平稳。非洲和南美洲锰矿成矿条件优越,可作为我国锰资源海外投资的方向。Manganese is a globally important basic bulk raw mineral and is also classified as a key mineral resource by major economies around the world.The types of global manganese ore deposits can be classified into five types:marine sedimentary,metamorphic,volcanic(hydrothermal)-sedimentary,hydrothermal and epigenetic,with the Proterozoic and Cenozoic being the main periods of mineralization.The global distribution of manganese deposits is uneven,mainly concentrated in South Africa,Australia,Brazil,Ukraine,Gabon,China,India and Ghana,etc.High-quality and high-grade manganese ore are mainly concentrated in four countries,namely South Africa,Australia,Brazil and Gabon,which are also the main exporters of manganese ore to China.In this paper,the characteristics of manganese deposits in the above four countries and the Xinjiang region of China are sorted out and summarised,and the global supply and demand pattern of manganese ore is analysed.In recent years,the global trade volume of manganese ore has been steadily increasing,and the export volume of manganese ore from South Africa,Gabon,Brazil and Ghana to China has increased significantly.At present,the investment in the exploration of major manganese ore resource countries is at a low level,the manganese ore market is relatively deserted and the price is relatively stable.Africa and South America have superior conditions for manganese ore formation and can be the direction of China’s overseas investment in manganese resources.
