(一) 云锅公司第二冶炼厂多年来试验并建厂处理选矿尾矿,用还原焙烧——常压氨浸出——蒸馏——重磁选工艺流程,获得氧化铜精矿,锡精矿和铁精矿的综合利用工作进展显著。试图对现有技术进行革新,采用不溶阳极电解铜铵溶液直接获得阴极铜。已实现的稳定指标是:电流效率85%以上;直流电耗2000度/吨铜以内;工作槽压1.6～2.0伏;电解废液残铜(多级电解)1克/升以下;电解铜片质量符合国
(I) The Second Smelter of Yunpan Company has tested and built the tailings for dressing and dressing for many years. The process of reduction roasting - atmospheric ammonia leaching - distillation - heavy magnetic separation was used to obtain the copper oxide concentrate, tin concentrate And the comprehensive utilization of iron concentrate work has made significant progress. Attempts to innovate the existing technology, the use of insoluble anode electrolytic copper cupric solution directly obtained cathode copper. Achieved stability indicators are: current efficiency of 85% or more; DC power consumption of 2000 degrees / ton of copper; working tank pressure 1.6 ~ 2.0 volts; electrolytic waste residual copper (multi-level electrolysis) 1 g / L or less; electrolytic copper quality In line with the country
