摘　　要：铌钽铷是非常重要的稀有金属,不仅在军事工业和科学技术领域,而且在民用领域有着广泛的用途。我国最近在内蒙锡林浩特石灰窑发现了大型的花岗岩型铌钽铷多金属矿床,其中Ta_2O_5和(Ta,Nb)_2O_5平均品位分别为0.0148%和0.0262%,Rb_2O平均品位0.163%,初步探明总金属量超过87万吨,潜在经济价值巨大,且外部开发建设条件和开采技术条件有利,进一步勘查和开发潜力较好。该矿床的发现不仅能将推动该区的经济发展,而且对我国稀有金属资源勘查与开发具有重要的指导意义。Niobium（Nb）-Tantalum（Ta）-Rubidium（ Rb）, which are distinctly important rare metals, have not only been widely used in military and science-technological fields, but in civilian areas. Recently, a large scale of granitic Nb-Ta-Rb polymetallic deposit with an initiallly explored total amount of 〉870000 tons and average grade of 0. 163% Rb20, 0. 0148%Ta2O5 and 0. 0262% （Ta Nb）2O5 has been found in Shihuiyao region, Xilinghot city, Inner Mongolia, China. This deposit has significant potential economic values and satisfactory conditions of external development and construction as well as and mining technology-, indicating its good potential of further exploration and development. In this sense, the discovery of the deposit can not only promote the economic development of the region, but have a significant guiding significance to the exploration and development of rare metal resources in Chin~_
