南京谷里铜矿于1972年投产。开始生产时,选别指标不高,铜精矿品位和铜回收率仅为14.54％和94.46％。随着生产工艺的不断完善,工人操作水平的提高,选别指标有所上升。1980年以来,在车间内推行了全面质量管理,通过整顿组织,加强管理,组织技术攻关,取得了一定的效果。在铜回收率下降幅度不大的前提下,铜精矿品位逐年上升。1982年达到
Nanjing Valley copper mine put into operation in 1972. At the beginning of production, the sorting index is not high, copper concentrate grade and copper recovery rate was only 14.54% and 94.46%. With the continuous improvement of production technology, workers improve the level of operation, the sorting index increased. Since 1980, total quality management has been carried out in the workshop, and some achievements have been achieved through rectifying the organization, strengthening management and organizing technical research. In the copper recovery rate decreased marginally, the grade of copper concentrate increased year by year. Reached in 1982
