Default 废铜回收再生加工方式

由于废铜回收可以再生,从而有较高的价值。例如,清洁的1级废铜回收的价格可以达到新精炼铜价格的90%以上;黄铜新废 料的价格也可达到相应黄铜价格的80%以上。
世界上废铜回收处理工艺及设备形成倾动炉火法精炼工艺加isa电解工艺的废铜回收先进处理工艺。目前世界上 最大最先进的废杂铜精炼厂,它采用一台倾动炉(350t/f)和一台反射炉(200t/f)处理废杂铜,采 用isa工艺(dk=313a/m2)生产阴极铜,产能17万t/a。
我国与国外先进的再生处理工艺相比,对废铜回收的预处理及再生利用工艺及装备整体水平落后,废铜回收的预处 理及再生利用两大环节脱钩,我国至今没有一个从废铜回收拆解到阴极铜精炼的完整废杂铜工厂,桑拿沙发,废杂铜精炼工厂厂多规模小、工艺落后、装备差、环保问题严重。我国至今没有一座现代化的杂铜精炼工厂或车 间。这些工厂规模一般在0.5-3万吨级,火法精炼基本采用反射炉,炉能25-110吨大小不等,这种炉子热效率低、能耗大,还原作业时黑尘污染严重,工人劳动强度大。产品质量只能达到 甚至低于gb/t467-1997标准中标准阴极铜的水平。相当数量的高品位废铜回收未经精炼即被直接生产铜线锭和铜"黑杆"。
江铜、云铜、铜陵、大冶等以处理铜精矿为主的国内大型铜企业也将的参与必然加剧国内回收废铜原料的竞争,冲击中小废杂铜企业.江铜将引进先进的倾动式阳极炉,建立专门杂铜处理车间,作为实现公司十五 总体规划的重要措施。
