| 摘 要： | 云南汤丹铜矿含铜品位低(平均含Cu0 64%)、氧化率高(>70%)、碱性脉石含量高(CaO+MgO>40%),而且嵌布粒度很细,给矿石加工处理带来很大困难。通过"九五"科技攻关,在试验研究的基础上建成了一座年产500t阴极铜的试验工厂,1997年底投产。本文叙述了采用氨浸—萃取—电积工艺处理汤丹高碱性脉石氧化铜矿的工艺流程和关键技术,重点叙述了试验工厂的操作和主要技术经济指标。

STUDY ON TREATMENT OF TANGDAN REFRACTORY COPPER OXIDE ORE WITH HIGH CONTENT OF ALKALI GANGUES |
| |
| Abstract: | The ore from Tangdan copper mine in Yunnan has low copper grade(average Cu 064%),high oxidation ratio(>70%),high content of alkali gangues(CaO+MgO>40%)and fine size of dissemination,so it is difficult in processingBase on research and experiment,a pilot plant with an annual output of 500t cathode copper went into operation in 1997This paper presents the technological flowsheet and key techniques of which the copper oxide ore is treated by use of ammonia leaching extraction electrowinning process,particularly the operations and main techno economical indexes of the pilot plant |
