Lithium, beryllium, niobium and tantalum are the main raw materials for the development of rare metals industry. Quite a long time after the founding of new China, the capitalist countries to lithium, beryllium, niobium, tantalum and other rare, rare earth metal products as the strategic materials on China's blockade, embargo, so countries decided to self-reliance, based on the domestic mineral resources, the development of China's rare, rare earth metal industry.

Lithium beryllium nb-ta mineral exploration, mainly through regional reconnaissance prospecting evaluation, exploration and key mining area, the combination of the geological and geophysical-geochemical, well drilling, drilling, pitting and other technical methods for exploration. Especially because rare rare mineral elements distribution, composition is complex, subtle ore granularity is embedded, the naked eye is not easy to identify, sand and rock ore appraisal and analysis, chemical analysis of detection, evaluation, exploration and rare, rare earth deposits and cooperate with the mineral intergrowth test plays an important role. The geological exploration of rare and rare earth deposits is carried out according to the exploration norm, and the exploration method and exploration project are chosen reasonably by exploration type. In China, the standard for geological exploration of rare metal ore deposits is divided into four exploration types, which are divided into three exploration types.

The exploration types of rare metal endogenous deposit and weathering shell deposit are divided according to the scale of ore body, morphology and the degree of mineralization uniformity.
