从发展稀有金属工业看矿产资源勘查开发前景

根据对我国２０１０ 年主要稀有金属品种需求量的预测，进行了资源配置研究。按开采２０ 年计算，以产储比１ ：４０ 配置经济可采储量：稀土（ ＲＥＯ） 为２１５ 万ｔ；锂（Ｌｉ２Ｏ） 为４３ ．５ 万ｔ；铍用量有限，暂未做资源配置；铌（Ｎｂ２Ｏ５）４ ．４ 万ｔ；钽（Ｔａ２Ｏ５） 为８ ０８８ｔ。现有资源保证程度，稀土、锂、钽可以保证，但贫矿多富矿少；铌无保证，缺乏可供开发以铌为主的富矿。

VIEWING OF THE PROSPECT OF EXPLORATION AND DEVELOPMENT OF MINERAL RESOURCES FROM RARE METAL INDUSTRY

The rare metals and their materials play the important strategic role in the enhancement of national economy and national defence power. Based on the forecast of demanded quantity of rare metals made by the departments concerned, the collocation of mineral resources is studied. On the basis of mining period of 20 years and output-to-reserves-ratio of 1:40, the collocated workable reserves are summarised as: REO 2 150 000 ton, Li 2O 435 000 ton, Nb 2O 5 44 000 ton, Ta 2O 5 8088 Ton. With regard to the current guarantee degree, the reserves of REE, lithium and tantalum will be assurable, but that of niobium will not.
