我国铌矿资源供需形势分析

Analysis of the niobium resources supply and demand pattern in China

我国保有铌资源储量536万t,主要分布在内蒙古、广东、广西、湖南、湖北地区,但品位低、开发利用程度低,铌精矿产量仅在50t/a左右,铌进口对外依存度高达95%。近年来,随着铌在超导材料、航空航天、原子能等领域的应用,铌消费量持续增长,预计2030年将达到2.35万~3.36万t。今后应加大对铌矿资源的地质勘查投入,加强与科研院校和地学合作研究中心的合作,提高开采和应用效率;同时,借助"一带一路""金砖国家领导人峰会"等国际合作平台,推进与巴西、加拿大等国在铌矿勘探采选、冶炼加工以及运营管理等多产业链的全方位合作。

The reserves of niobium resources in China are 5.36 Mt,mainly distributed in Inner Mongolia,Guangdong,Guangxi,Hunan,Hubei et al.However,low grade and low development and utilization degree makes the production of niobium is only about 50 tons a year,and the import dependence of niobium is up to 95%.In recent years,with the application of niobium in superconducting materials,aerospace,atomic energy and other fields,niobium consumption has continued to increase,and it is expected to reach 23.5 thousand tons to 33.6 thousand tons by 2030.Therefore,it is necessary to increase the exploration input of niobium mineral resources,strengthen cooperation with research institutes and geoscience cooperation research centers,and improve the efficiency of mining and application.At the same time,with the aid of“Belt Road”“the BRICS Summit”and other international cooperation platform,it is suggested to promote all-round cooperation with Brazil,Canada and other countries in all industry chain such as exploration of niobium acquisition,smelting,processing and operating.
