| 中文摘要: |
| 刁泉银铜矿是一个伴生金的大型次火山岩型矿床。矿石中的金银主要以金银的独立矿物形式存在,少数以类质同象赋存于黄铜矿、斑铜矿、辉铜矿、黄铁矿和方铅矿的晶格中。金银独立矿物的种数多达11种以上,并以铜的硫化物为其主要载体,因而在选矿时金银大部分进入铜精矿中,其回收率均在85%以上。 |
| 英文摘要: |
| Diaoquan silver-copperore deposit is a large-scale subvolcanic type deposit with gold as by-product. Au and Ag in ore occur mainly in more than 11 Au-Ag minerals; a few in lattice of chalcopyrite、 bornite、 chalcocite、 pyrite and galena in isomorphism. Various Cu sulfides are the main carrier of Au-Ag minerals and therefore Au、 Ag are amassed in Cu concentrate and recovery of Au、 Ag are more than 85%. |
