我国钨矿资源及其开发概况我国钨矿资源丰富,到目前为止,已发现几千个钨矿点。而做过工作、有探明储量的还不到总数的1/5。绝大部分矿床(点)分布在华南地区。矿床的成因复杂,类型繁多。华南钨矿,根据其成矿物质来源,成矿条件和矿床产出特征等,可划分为四系七类十七型。在我国,钨矿的开采历史悠久,但正规的机械化生产则是解放后才开始的,自从1952年建成第一座钨的机选厂
Tungsten resources in China and its development overview Tungsten rich in resources in China, so far, has found thousands of tungsten ore point. While doing work, there is less than one fifth of the total proved reserves. The vast majority of deposits (spots) are distributed in southern China. The causes of the deposit are complex and varied. South China tungsten ore, according to its source of mineralization, metallogenic conditions and the characteristics of the output of the deposit, can be divided into four series of seven types of seventeen. In China, the mining of tungsten ore has a long history, but the formal mechanized production started after liberation. Since 1952, the first tungsten machine plant was built
