冶山铁矿选矿厂1972年投产以来,选铜技术指标一直较低,1978年～1981年平均指标仅达到:铜精矿品位12.58％,铜实际回收率48.16％。生产实践表明,采用浮选柱作为铜钴混合浮选设备,不适应我厂浮选工艺的要求,于1981年8月以浮选机取代了浮选柱,铜的回收率有了较大幅度的提高,连续八个月的选铜的平均生产指标达到:铜精矿品位12.47％,铜实际回收率56.51％。
Since the ore dressing plant in Ye Shan was put into operation in 1972, the technical indicators for copper selection have been relatively low. The average indicator from 1978 to 1981 only reached 12.58% copper concentrate and 48.16% copper. Production practice shows that the use of flotation column as a copper-cobalt hybrid flotation device does not meet the requirements of our plant flotation process, in August 1981 to replace the flotation column flotation column, copper recovery rate has been more substantial The average production index of copper for eight consecutive months reached 12.47% for copper concentrates and 56.51% for copper.
