摘　　要：介绍通过现场生产工艺条件改进 ,显著提高了多项生产技术指标。铜精矿品位由17 67%提高到 2 6 35% ,铜精矿含锌由 12 4 3%降到 7 74 % ,铜精矿由含锌超标的废品变成质量较好的合格等级品。锌回收率提高 5 11% ;铅回收率提高 2 37%。企业获得显著经济效益。Most of the production indexes are raised by improving production technology condition on site. The grade of copper concentrate increased from 17 67% to 26 35%; the zinc in copper concentrate decreased from 12 43% to 7 74%. Copper concentrate was waste in the past because of containing too much zinc, but now it becomes qualified production. The zinc and lead recovery increased 5 11% and 2 37%, and the enterprise gained more profits.
