| 中文摘要: |
| 杏枫山金矿位于湘中白马山—龙山—紫云山金矿带的西段,是湘中地区重要的金矿之一。相对于湘中龙山金矿、大新金矿和铲子坪金矿而言,杏枫山金矿研究程度较低。尽管前人已有的研究表明,该区金的品位与含脉密度和毒砂含量呈正相关关系,但目前尚无人对该区毒砂进行任何研究,该区毒砂的特征及毒砂中金的赋存状态目前尚不清楚,这严重制约了选矿过程中金的回收率的提高。文章拟对杏枫山矿区毒砂进行矿物学研究,探讨毒砂中金的赋存状态,揭示毒砂与金的成矿关系,这对推动该矿改进选冶流程,提高金的回收率,具有非常重要的意义。 |
| 英文摘要: |
| The Xingfengshan gold deposit is located in the western part of the Baimashan-Longshan-Ziyunshan gold belt in central Hunan,which is one of the major gold deposits in central Hunan,while the study of this areawas at the lower level degrees among the Longshan gold deposit, Daxin gold deposit and Chanziping gold deposit.Although historical work show that the Au grade has a positive correlationwith vein density and arsenopyrite content, there is no any research on arsenopyritebefore.We do not understand arsenopyrite features and the gold state within the arsenopyrite, which curbed the Au recovery rate during the concentration process.This thesis intended to conduct mineralogical studies on arsenopyrite in the Xingfengshan mining area to discuss the occurrence of gold within the arsenopyrite and reveal the relationship between arsenopyrite and gold,which is of great significance to promote the procedure of improvements metallurgical and the Au recovery rate. |
