山西省冶金局受冶金部委托,于1979年6月20～23日在中条山有色金属公司召开铜矿峪提高铜精矿品位试验鉴定会。出席会议有厂矿、科研、设计、高等院校等10个单位的代表33名。提高铜精矿品位、降低二氧化硅含量的试验是为了满足铜矿峪矿扩大生产规模和新建第二冶炼厂的需要。经冶金部批准,中条山有色金属公司矿冶研究所和北京有色冶金设计研究总院于1978年6～9月在现场做了一段磨矿、中矿再磨、粗精矿再磨等
Metallurgical Bureau of Shanxi Province commissioned by the Ministry of Metallurgical, in June 1979 from 20 to 23 in Zhongtiaoshan Nonferrous Metals held a copper mine to enhance the copper concentrate grade test appraisal. There were 33 representatives from 10 units including factories, mines, scientific research, design, colleges and universities attended the conference. To improve the quality of copper concentrates, reduce the silica content of the experiment is to meet the copper mine to expand the scale of production and the new second smelter needs. Approved by the Ministry of Metallurgical, Zhongtianshan Nonferrous Metal Mining and Metallurgical Research Institute and Beijing Nonferrous Metallurgical Design and Research Institute in the field from June to September 1978 made a ground grinding, mining re-grinding, roughing and then grinding
