近日,内蒙古自治区地勘一院在武川县赵井沟大青山探明一大型稀有金属铌钽矿床,铌加钽矿资源量超2000t,其中钽矿资源量估算达1000多t。经初步勘查表明,矿体受构造裂隙控制,形态较为简单,为脉状,走向呈北西向,倾向东南。钻孔见矿厚度在几十至上百米之间,矿体品位较富,局部矿体钽含量达0.1%。
Recently, a Geological Prospect of Inner Mongolia Autonomous Region proved a large rare-earth niobium-tantalum ore deposit in the Daqingshan Mountain in Zhaojinggou, Wuchuan County. The resource of niobium and tantalum exceeds 2000t, of which tantalum resources are estimated to be over 1000 tons. After preliminary exploration shows that the ore body controlled by the structural fissures, the shape is relatively simple, vein-shaped, the trend was northwest, southeast. Drilling to see the thickness of the mine between tens to hundreds of meters, ore grade is rich, local ore body tantalum content of 0.1%.
