| 中文摘要: |
| 斑岩型铜钼矿床除主要成矿元素Cu，Mo外，还往往共(伴)生Re，Co，Au，Ag等重要元素，综合回收利用共(伴)生金属具有重大资源及环境效益。通过研究斑岩型铜钼矿床中共(伴)生元素Re，Co，Au，Ag的品位、储量、赋存状态及分布规律，认为Co主要以类质同象形式赋存于黄铁矿中，其分布与黄铁矿密切相关，通常浓集于绢英岩化带外侧；Au，Ag主要以自然金、银与金银系列矿物的形式产出，Au，Ag在不同硫化物中的含量、颗粒粒度以及赋存形式差异很大，Au在各蚀变带均有可能富集，但主要浓集区域是钾化带与石英-绢云母化带；Ag在早期主要以Cu-Ag-Au的形式富集于绢英岩化带，晚期以Pb-Zn-Ag形式赋存于青磐岩化带；Re的分布与绢云母化带的辉钼矿密切相关。 |

| In addition to Cu,Mo the by-product elements, such as Re,Co,Au,Ag etc. could be recovered from Cu-Mo porphyry deposits. Recovery of the by-product elements is significant to both mineral resources and environment. Study on their grade and reserves,occurrence and distribution regularity draws a conclusion as follows: Co occurs mainly as isomorphs in pyrite which is often enriched along the outside of phyllic zone; Au and Ag as native gold,native silver or electrum,and content,grain size and occurrence varied greatly in different sulfides, Au enriched in different alteration zones but mainly in the potassic zones and quartz-sericitization zones, Ag enriched mainly in phyllic zone in the form of Cu-Ag-Au in the early stage and in the propylitic zone in the form of Pb-Zn-Ag in the late stage; Re closely related to molybdenite of the phyllic zone. |
