中文摘要:

      青海省大柴旦地区是我国硼资源主要产地之一,经数十年的开采,矿体中富矿已基本枯竭。通过对大柴旦地区硼资源的分析,重点介绍了分级富集与沉矿浮选联合流程法和直接分级法两种低品位硼矿富集技术,同时对两种技术的内容、路线以及创新效果进行了讨论,并由创新效果的比较分析,得出两种方法的优点和创新性,同时提出对未来低品位硼矿富集技术的展望。

英文摘要:

      Da Qaidam area of Qinghai province is the main distribution area of boron resources,but the boron minerals have been on the verge of exhaustion after decades of mining.Through the analysis of boron resources in Da Qaidam region,the authors introduced two kinds of low grade borate ore concentration technology which being grading enrichment with heavy mineral flotation process and direct grading method,and discussed the technical provisions,routes and innovation effect.By analyzing the innovation effect and the advantages of two methods,some process for the low grade borate ore enrichment technology are given.
