复合无机盐法分离铜包钢复合金属

摘要

铜包钢复合材料的出现在节约了大量有色金属，也带来了资源再利用的难题，为了减少复杂的物理回收方法带来的能源浪费和环境压力，实现资源的合理利用，借助合成氨工业上的铜氨液工艺，在催化剂的作用下，把铜包钢废弃物中的铜提取出来。经过滤、蒸发、浓缩、灼烧后转化为黑色氧化铜粉末，最佳配料比是Cu：NH3：（NH4）2CO3：催化剂为1：5：1：0．3。%The practice of using copper-clad steel saves a lot of non-ferrous metals, and brings problem of reuse of resources. In order to reduce energy waste and environmental pressures generated by physical recovery methods, and achieve rational use of resources, we extract the copper from the wasted copper coated iron with the catalyst, and the copper ammonia solution process in ammonia industry. After filtration, evaporation, condensation, burning, the copper converts to black Copper oxide powder, and the optimal charge ratio isCu：NH3 ： （NH4）2 CO3 ： and catalyst 1 ： 5： 1 ：0.3.
